If you had a one-way ticket to Jan 1, 1999 that departs on Jan 1, 2024, and you are allowed to bring whatever fits into a backpack with you, what would you bring to use to take over the world, and how

Simple. Im ripping up the ticket.

Since my actions have knock on effects and the ticket is 1 way that means Id have to abandon my wife and child and given how much my actions would change things, effectively unmake my daughter.

The worlds fucked, I might be able to unfuck it but theres a better chance Id just create a different flavor of shit sandwich. But to know Id never hear "Dayyydeee come pway wif meeeeee" again.

Fuck it. Let it burn.

If you got a camping backpack maybe you could bring them! That's my plan.
What would your response be if you could take your family with you?
- Id need seed money so Id get the lottery numbers for the biggest win shortly after I arrive, digital copies of the worlds financial newspapers for 25 years, some targeted stock info on companies like Google, Amazon, Apple, Intel, facebook and other "Big Tech" and media firms. Knowing when to buy certain stocks and when to dump them would allow me to slow grow myself into someone that could have serious levels of control over a vast number of industries with far reach.
  To make an impact with that reach, Id also have a serious SHITLOAD of research papers for anything related to green energy, cancer research and any other medical research that could save a shitload of lives. With 25 years of "leaps and bounds" in tech and medicine up my sleeve Id start a green energy company that knows which competition to buy and when, what "suggestions" to offer my researchers when I stop by for a visit. Same with biotech and medical research.
  Given 25 years Id be a global renewable energy mogul who has done more to cure cancer (especially in kids) aids and a host of other diseases than any other man in history, controlling significant portions of the mass media in every first world country I could get my hooks into AND with the ear of very serious people in academic circles... Id be a fucking kingmaker with such an amazing public persona that to come at me would be career suicide for anyone in politics.
Uh, no one said save the world. The assignment was to take it over.
- Dont want to do that either if it means abandoning my daughter. If I was going to do it I'm doing it benevolently.

We don't really know what would happen to this reality. It might just flicker and vanish away. But if you had a new daughter, she might be awesome too and without the time travel, would have never existed.
- That’s cool and all, but they love this daughter now.
There is a subplot in the INVINCIBLE comics that follows this very premise, and chooses the same decision you do for the exact same reason
That's kinda where I'm at. My wife is probably the entire reason I'm not either dead at my own hand or crazy. And meeting her was a complete accident.

Gray's Sports Almanac

Just hope your school bully doesn't find it.
- God forbid we end up on the 1985 timeline. Can you imagine if someone like Biff became rich and powerful?
- Why don't you make like a tree and get outta here.
- Oh la la!
It only had information up until 2000 so better make good use of it for that one year

I come with scientific evidence of the impeding doom that will be brought by climate change and urge the world's powers to reduce greenhouse gas emissions while there is still time! Surely everybody will listen to my proofs and act to protect the world!

Sure, Mr. Gore.
- [Monkey's paw curls]
We already had that evidence by the 1960s!
- I'm pretty sure someone wrote about it in the 1900s, like 1908 even
Honestly it might be better to bring proof gore is better than bush or they he won florida
LOL. It would be easier to just become the richest man in the world and buy politicians
This time will be different

Lottery numbers and a historical record of the stock market: first, win lottery then invest based on performance

Become a billionaire, then join the oligarchy and use my stock knowledge to bankrupt the rest of the oligarchy

At some point, wouldn't having future knowledge of the stock market either lead to you changing the stock market with the presence of your money until your predictions lose their accuracy, or else get you investigated for insider trading due to it being statistically insanely unlikely to be that lucky?
- You could just spread it across a bunch of GICs and then ETFs that were solid performers. You have your lottery money, you just need to earn enough to live the way you want. With enough invested but diversified you could make a fortune without influencing anything as a result of personal choices.
  If anythjng, the initial lottery win will have the biggest impact on the timeline, assuming you lay low afterward.
  Now, here's the thing. I'd say you would be sharing those winnings with the original winner unless you prevented them from getting the ticket so find a jackpot twice as big as you need and hope a bunch of yous from alternate timeline don't get the same idea.
  That's what would happen to me and I'd end up winning about $3.50.
- I think as long as you’re careful you could avoid crashing the market until you are ready, and they would have to prove insider trading. I could spread my stock purchases through a bunch of shell corporations as well
- Don't go all in to try and be the majority in a ton of things, and good luck PROVING insider information.
  Besides if you make enough money, you can just make investigations go away as long as you aren't too flashy about it. Or have a convenient distraction story waiting elsewhere to divert attention away from yourself.
... It freaks me out that is exactly my plan that I've spitballed in the shower several times.
- Cia_chatbot knows.
Bear in mind that logically, the longer time goes on and the more you interfere, things will diverge. You might only be able to win the lottery a handful of times before the butterfly effect starts giving you numbers which don't match your predictions from the future. I figure the same thing happens with investments. If someone buys a tonne of shares using billions, the history of the stockmarket will change and over time be unreliable outside of certain events. Might be wise to buy up aquire certain talent though.
- make your billions by buying lots of small, but super profitable investments.
Yeah, just buy Apple, Amazon, Google and Facebook when it comes out and you’re all set.
- Also, start generating Bitcoin in late 2009 and sell it all on Nov 10, 2021.
Just buy Apple and Microsoft. You'll be fine.

$20 cash to buy bitcoin

That’s enough. More than enough money to never work again and info to help stop 9/11, etc…

$20 cash to buy bitcoin
Bring a 2023 model computer back with you and you could just mine all the bitcoin yourself.
Hell, you could even temporally-plagiarize Satoshi Nakamoto and invent it yourself.
- This is a great idea but it requires effort and if I were to mine 10billion bitcoin very early, that may change the future of bitcoin such that it never hits 30k+ value per. It seems safer to simply buy 1000 of them at a $0.10 to resale at 10k+.
  My plan is minimal effort, minimal impact to anyone that isn’t me, and to get all the money I could ever need.
Your smartphone probably has a comparable amount of processing power to some of the earlier mining farms. May as well just mine the bitcoin
Win the Powerball more than once and someone will be doing an investigation.
- Oh yeah, definitely. I’d take all the numbers because I’d assume at some point history would change such that the record wouldn’t be perfect forever.
  I’d win one that is over a billion. Then quit.

A healthy 21 body and 1999? Fuck taking over the world, and I don't need your stinking backpack, just tell me where to get that ticket and where to show up, I'm not going to miss this! I'm taking a cyanide pill though when 2020 rolls around; I'm not doing this shit again.

So prevent it from happening!
- One of the reasons why the coronavirus vaccine was created so quickly was that the work was already 90% done.
  If you orchestrated things that you would be a billionaire by the 2010s, you could purchase the company that designed the vaccine and make sure that they are appropriately funded so that the vaccine for coronavirus would already exist at the time the pandemic struck.

Grays Sports Almanac

I would have no inclination to take over the world. But if I could go back to that date, I would make a million different decisions over the next few years to steer my life in a much wiser direction.

Get every flagship CPU and GPU from 2000 to today that I can get my hands on. Also as much open source code as I can get hold of. And especially AI stuff - there's several fully open source models, so bring those, and as much technical writings on them as possible.

Speaking of which, download every science paper published since 2000 that I can get hold of, in every possible field.

Get as much info on the 2000 election as possible, to hand to Al Gore, see if he can win that election with a solid unassailable margin.

Research stocks, lottery, and everything else I can to get fast money within the shortest possible period of time after I get there, so I can get super rich before the butterfly effect makes predictions impossible, I need billions in seed money and I need it fast.

Then use that money to start a private research group, and hand them all the scientific papers I brought. Get those experts to work studying all this knowledge and figure out what can be turned into practical technology. Turn some of this into profit-making devices to fund continued development, but release as much as possible for free.

Essentially, deluge the world in as much new technology as possible, mostly free and open source, holding back only as much as necessary in order to fund continued research.

And oh jeez the pharmaceutical industry. Release for free every drug made since 2000, so the pharmaceutical industry can't get their patents in them.

Big list of stuff there, but if I pulled off even half of it, the world would probably be a much better place in 25 years than in my original timeline.

It's a really smart way. Very interesting, and I agree. It would probably be the best course of action.
I only wonder how quick the butterfly effect would have effects on your "future" documents.
For example, helping Al Gore win could drastically change the imminent future.
- That's why most of the stuff is technical or scientific information for the researchers; things that aren't subject to change, just technical info. The money stuff I would hope to manage in less than 6 months from my arrival, because even in that short time I'd expect a lot to change by the end of it.
  It'd just be a question of getting that initial funding off the ground with which to set up my research institution. After that, the few things I don't release for free should cover expenses.
  Sidenote since I didn't address it in the original reply, taking over the world is impractical even with future knowledge, but as the person in charge of this outfit that would quickly be the world's most advanced research tank, I'd probably have a lot of influence, which is the best anyone can practically hope for, I imagine. A lot more than the last 25 years of advancement would be needed to actually take over I figure.
Get every flagship CPU and GPU from 2000 to today that I can get my hands on.
What use is that? Without the asml duv lithography machine, no one could duplicate it. And you'd have no motherboard to plug those chips into.
- Honestly, I don't know for sure since I'm not an expert; my reasoning was the hope that being able to examine the entire line of advancement would allow the necessary technical knowledge to be extracted and duplicated. I knew that just bringing the latest one would definitely do nothing.

An entire offline copy of Wikipedia up to Jan 1 2024 on a tablet. Having all the world events up to that date available to consult at my fingertips, I could use it in so many ways.

Don't forget a charger, otherwise you'll be screwed for awhile
- USB 1.1 was already around in 1999, USB 2.0 being released in 2001 with Mini-A/AB/B being available in 2001, and the standard Type-A as early as 1996.
  Take one of those USB Type-A to USB-C and you're good enough until circa-2008 when USB-C starts to get around

Information is power. A simple smartphone loaded with major historical decisions, sports results is enough to make you a billionaire. Take some tech textbooks to stay ahead of the game, maybe some newly developed medicine.

Given that the AIDS epidemic was still in full swing at the time, just being able to teach medicine makers how to make pRep would make you a billionaire just from the licensing fees.
- What's that? Profilactic?
  You can just take back the experimental vaccine and save some people.
Just thought Kiwix seems like it'll be handy here, it lets you download Wikipedia and some other websites, and they have an Android app to view them.
(They have a web version too, which I actually selfhost for if the world ends or something /s)

Greys. Sports. Almanac.

The only correct answer.

I've got no motivation to take over the world, nor am I sure it's really possible in a life time. I don't really have a non-boring answer to this hypothetical.

If the ticket is available anyway I'd happily take it, I'm single at the moment with no dependents and being younger and healthier would be huge. There are lots of ways to make money with the knowledge of future history, even if it'll change when you start impacting it, and any one of them could make me wealthy enough to never have to work again in my life and do so wherever I please.

I've never really understood the need of the rich to continually amass wealth or how they spend it.

Invent Apple Google and Amazon all at once. Yes, I know they all existed at that time but I would just do their best ideas before them.

New Pied Piper
Why not go with original ideas like Facebook, Uber, Bitcoin, YouTube and ~~Reddit~~ Lemmy?

stock data

Bitcoin has outperformed stocks by about 100,000-fold. All you need is a fiver to invest at the beginning.
- Note that that return is only for the early investors. If you are incredibly lucky and we have a very flush couple of years you might triple an investment in by 2030 now. But you are also very likely to just lose it All

Probably a backpack full of smart phones, go sell them and retire.

Then cry that it'll be a long time until I can use USB C again.

That's a good idea but I wonder if anyone would buy them? Obviously the technology inside of it would be a quantum leap for any tech company that could get their hands on it. AT&t or ma Bell or Motorola would all easily fall over themselves to hand you several million dollars for it just so that they could have their top researchers reverse analyze the equipment.
The downside to that issue though is that it would be very difficult to get in contact with the right people to sell these devices at the right price.
- Any current smartphone would be the best digital camera that exists by a mile, even if they didn't have Internet access.
- That kind of technology is hard to get any value from. Nothing in modern phones is innovative, and most of it would be an obvious evolutionary step to any specialist in their field.
  Mostly, though, the phones would be useless. Cellular networks were in their infacy, and none of the standards or technology existed to charge them. Reverse engineering anything in them would be hugely expensive, for little return.
  Smart phones would be interesting, but far less interesting than the existance of a person who has access to future technology. I think op would dissappear into a government facility not long after trying to pawn their goods.
- I mean I could always post photos on Twitter and... Oh wait.

The bag is full of post-1999 MTG cards that I will trade for pre-1999 MTG cards.

A person of culture, I see.

Cobain would have been dead for nearly 5 years at that point
Yeah, chilling seems like a much better use of time

All the FLOSS software i could put my hands on (with source code), a couple awesome smartphones, wikipedia dump, sports almanac, and a stable-diffusion rig.

I'm curious how stable diffusion plays into taking over the world.
- I don't know about stable diffusion but I know deep fakes would be handy. Being able to release videos to the public while retaining my privacy would be invaluable.
  And if the CIA or the KGB decided to assassinate my alter ego they would have a hell of a time even finding the fucker and if they did find somebody that looked just like them and executed them that wouldn't have killed me.

I would bring Wednesday 6th January 1999's winning lottery numbers, five books chronicling the last 25 years of British history, history of businesses, history of the tech industry between 1998 and 2023, modern military history, and the history of Blackrock. Also I would choose a healthy 21-year-old body.

The plan is... win the lottery for some immediate starting capital, make well-informed investments, effectively become the Warren Buffet of Britain and weasel my way into the world elite, befriending figures like David Cameron, Tony Blair, Jeffrey Epstein, Bill Clinton, etc. I would make timely investments into new startups like Facebook, Twitter, etc, jump on the Bitcoin, Dogecoin and Ethereum bandwagons early and make it my aim to become the richest man in the world. With that wealth I'd then buy more shares in Blackrock, Blackwater and Lockheed Martin, seemingly be at the top of my game as head of a PMC. I would assist in conflicts that maintain the status quo as best as I could.

I would also do a tonne of work with African military forces, make loads of private investments in African firms and , and beat China to the punch.

With the exception of Blackwater, I would not aim to be a majority shareholder in any of these companies. I'd keep maybe... 5 to 10 percent of shares in the really successful companies, lose a bit of money in falls to not arouse too much suspicion, but I would otherwise climb to the top of the PMC ladder and put my fingers in as many NATO pies as possible.

That's what I'd do if my aim as a time traveller was to take over the world. In actuality, I'd rather just win the lottery, diversify my investments and retire comfortably. I don't desire world domination.

A current download of Wikipedia.

A computer with lists of winning lottery numbers, stock prices by day of all major companies, archived copies of webpages or, preferably, scanned in newspaper articles of all world events from 1999 until now, and lists of every politician and individual with net worths over $300 million.

Also patents for LCD screens, the microchips in use in the 10's and now, the efficient solar panels China cranks out if I can get a hold of that information, modern efficient wind turbines, etc. Also important scientific papers written between then and now, especially for Ozempic and Wegovy.

Also, this might be the one practical use for dumb shit like Chat GPT and its ilk, so we're bringing along a couple of GPUs and copies of each major open source AI I can scramble up.

I use this information to:

Hopefully prevent 9/11
Become filthy fucking rich
Infiltrate the elite and start bumping off motherfuckers one by one Count of Monte Cristo style
Distribute my ill gotten gains to the masses and use the rest to stop climate collapse

#EatTheRich

Please don’t get rid of 9/11, without it we wouldn’t have WKUK
- They are so talented they did not need 9/11 to have a hilarious TV show

A Lenovo P series with deepfacelab. I would work public perception of Dubya (and Jeb) to avoid the decades of war crimes.

To take over the world? I'd take the records of every international technology and medical patent. And, a cell phone. I'd get the local news interested in my new handheld PC, find the least scrupulous tech company which reached out to me, and hatch a plan to create a trillion dollar tech empire.

A modern desktop PC full with top of the line deep learning graphics cards.

I will flood the internet with helpful comments, exploits, anything that will take down the banking grid. I will sway online and print media discourse towards progressive politics. I will take down Murdoch media and ensure that he never again makes a cent spreading his rhetoric.

I will start a consulting company using my AI models as my employees and make unspeakable amount of money, whilst ensuring that large contracting firms never take off.

I will buy up large linear strips of country, and build railroads and rail stations everywhere, whilst building free accommodation above and below the tracks to ensure that the homeless always have somewhere to sleep, and to ensure that buy-to-let landlords can never return much on their investment.

I will crash weapon trading stock markets, exploit the emails of corrupt politicians and their billionaire donors. I will wage financial war on the 1% until the world gini index reaches 0.5

Pingy Putty and Reaganism would all still be in heavy effect, I can't think of a way any one person is going to bring down 3 nuclear super-war-states. We don't have any anti nuke tech eminence in shadow but nice writing prompt for potential suffering trying.

Pingy putty? I've never heard of this before.
- Putin and Xi Ping would still be serious threats to trying to take over the world even from 1999 perspective.
- Also, nothing comes up when I search it on DuckDuckGo or start page
Eminence in Shadow? I only know the term from the anime. What does it mean here?
- Trying to Isekai to 1999 to take over the world brain.

1989 would be better. 2000s were pretty terrible.

You have to prevent 9/11. Then you can still walk your grandma to the terminal when she flies to the Bahamas.
- Prevent Gore losing
89 was a good year. I didn’t quite have bills yet.

I'd take the entirety of the USA's military hardware. Nobody said how big the backpack was.

You have to be able to walk 100 meters while holding onto the backpack, it has to be strapped to your back, and it has to be a commonly available backpack of a variety purchaseable in a store with the next 25 days.
No part of it can touch the ground, nor can anything attached to it other than your feet and shoes touch the ground, and everything that you have must be fully enclosed by the backpack, and you must cross through the portal on your own two feet.

I assume I get ID for a person born in '78 if I choose the adult body? I was born, but very young.

Hard drives of data compatible with old computers, and a few modern laptops for good measure. Maybe some electronics equipment too in case I really need to interface with something obsolete or proprietary. Some period-appropriate cash to live on before my first "job". The 2000's won't know what hit them.

I'm not going to be able to take over the world (shit, even taking over Afghanistan proved to be too hard), but I sure as hell can be a shadowy hacker figure that steers the course of history. I'll probably avert 9/11 assuming I can get up and running fast enough, and try to steer China towards reform and detente with the West. Russia's probably intractable. I wonder if I could tip the Florida election towards Gore, in order to get global warming taken care of faster. Giving a bump to renewables research could also help things along.

Edit: So, there would be a lot of phases to this, as I gradually shift from being anonymous to a hot item. Once I reach some point at or after present day, I'll publish my archives so the world can decide for itself, and I'll leave proof early on that it's genuine, for example as hashes of data in things like newspapers that are well archived. Then I'll dismantle my cabal and retire.

I'm squashing my partner into a very large backpack and taking them with me.

I don't think I could take over the world so I choose love. But I can't resist the new body part which is why I'm not just staying here.

Don't worry, they can get a ticket and a new body too, but between the two of you you can still only take one backpack.
- @Bizarroland thanks, that's great!! I think we'll probably put a couple of reasonably modern computers, components, and drives containing information into it, and paper printout backups of the things I need most, and whatever pharmaceuticals I can get my hands on for retroengineering.
  A 24 year jump on scientific and tech research might not help me take over but it could at least make the world a better place. ART for HIV in developing nations for starters.
  I'm guessing the butterfly effect probably applies to lottery numbers, but the stock market's likely still good to go, and that can fund me (along with a few non essential drugs I can sell to pharma) so I can be more influential.
  I was already an adult in 1999 so I will know my way around just fine.
I read this as 'new part of the body' and was wondering what new part you'd get (like is it also an optional gender switch? Or perhaps you're an amputee?) but then I figured out oh, okay, you mean the part about the new body.
- @squiblet yeah I could have worded that better!

My phone, laptop, charging cables, ethernet cables, tons of SSDs to use with said laptop, Kali, and a bunch of cyber-sec resources.

Having a $2000 2023 gaming/workstation laptop would be an insane amount of computing power in 1999. Being able to use modern-day exploits and discoveries in 1999 would probably allow me to gather as much intel as I needed from my targets while not being discovered. If something gets patched by a Windows XP service pack, I'll still have an endless list of exploits that work. Hell, I'd even have access to something like Spectre and Meltdown, and that's something that still must develop organically.

Reflecting on my own actions and the folks I met on the way, taking a better attitude would help a lot. I was young and had good conversations with different types of people but did nothing with that for close to another 15 years.

We had much of the information then, IMO. And I remember talking with much older folks who were willing to listen to teens/young adults about a variety of topics. I just wasn't willing to say anything. Even to my peers.

I would take a better attitude.

Can I fill it with whatever I can think of or only things I actually have right now?

Anything you can acquire, legally or not, and have in your possession on Jan 1, 2024.
If you end up incarcerated or dead between now and then, the ticket is null and void.
- Oh well, so much for filling my backpack with rhodium.

I would bring a laptop with a good CPU and GPU, an ASIC Bitcoin miner and 10,000 in cash in case for some reason the miner broke or didn't work.

I would bide my time at pizza delivery jobs for 10 years paying rent living on ramen and buying small amounts of gold and silver coins. As soon as the first btc client was released by Satoshi I would start mining. I would be selling things on the cheap and performing services as much as humanly possibly. Id have a small gold and silver for BTC company, selling $50 gold coins for the equivalent of $25 in BTC at the time. I would not stop until I had at least 1,000,000 Bitcoin, or January 2017, whatever came first. As soon as the BTC rush of 2017 starts, I start selling my BTC en masse at the peak. Mail order, cash, in person, whatever. Claim what I need to on taxes. Sell the rest via an exchange before it's regulated as a security and needs to be taxed.

Now I am a big time multi-billionaire and no one even knows my name besides my financial advisors and closest friends from my pizza delivery days who now work for me doing "whatever the fuck they want" work for 100k per year.

I keep investing in companies who sell the most in online communications services (zoom, Microsoft, etc), mask production, hand sanitizer, laptops, gold and silver, and whatever else I can remember. As a ride out COVID, I've increased my 5-10 billion to 20-30 billion.

Now I live a happy "do whatever the fuck I want" life at roughly the same age I am now, only now I have total freedom and power because of "20 years of hard work and foresight -- I started as a pizza delivery boy, and you can too ;).”

A few useful books about electronics, devices and new inventions and all of the electronics I can fit into my backpack.

Winning lotto numbers for years.

Like the other person mentioned their family, I would say that about my friends and other relations. I don't think it's possible for me to redo my life in a way that my decade old friendships would be the same (or even better) than what they became. I don't even know if I will feel the same about my friends if I decide to relive my life as memory is a precarious thing and I can't rely on how I feel about them to last until I meet them again and live life interacting with them while trying to change the world.

I could consider a 21yo body but as a millennial I would end up overaged for the people who were important in my life to have any meaningful relation with them.

I have considered the scenario of reliving my life, correcting my mistakes and maybe making some massive changes along the way, if I could somehow guarantee keeping the things that matter to me the same.

I forgot to write what things I would do, so here are some ideas:

Investing is an obvious one which everyone else has also mentioned.
I would download all the open source stuff, all leaked files, maybe even scour the dark web for stuff
Buy NeXt to hire jobs as the CEO of my tech company (also any other corporations that I could buy back then, like Google)
I'll create a note with ideas that were killed too soon or didn't last due to tampering by big corps, and products which got enshittified and implement them when there's no competition or wait for when I have enough money to not worry about people getting in my way.
I'll create a note with mention of all the important events (multiple notes, encrypted, to prevent someone from using that information)
Put an offline LLM and other AI on my phone (along with very reliable chargers and replacement batteries).
(Kind of a sub point of above, but it got big) I'll try to take a phone with replaceable batteries and sturdy design. It would be great if it could fit in that time, I'll disable the touch screen to that effect and only use a stylus, and other changes to make it seem worse or maybe take a "bad" phone from the start. I'll also claim it's an experimental product if someone asks me about it.
A list of my favourite recipes, so that I can be a food trailblazer
Start my own music company and invest in artists which I know will be big in the future, give them better terms than my competition and use that roster to prepare for streaming. I'll already have Jobs and Ive to design iPod and take over that period.
With RISC-V as my chip, I'll buy one of the fabs which went under back then and use it to establish myself as a chip manufacturer and once I have built up enough lead in the fab business with knowledge gathered before going back I'll open source RISC-V as an act of benevolence according to the world (I'll discuss the future fab knowledge with the researchers I will acqui-hire with the fab, they should be able to create something in a few years with whatever knowledge I can provide, I'll just have to act as a layman with more knowledge and if I go with my age they'll think I'm a smart kid)
I didn't mention crypto because that might change with the chip info I bring back, so I'll see if that happens again and invest early and secretly to have enough of it to have a hand in that too.
I'll also try to keep my identity hidden so that I can live the important parts of my life again as they were, and once I have lived those I'll consider if I need to be known to the world.
I'll prepare media organizations to fight disinformation
I'll bring back innovations in renewables that I'll slowly release into the world.

Forgot to mention in the edit, so adding as a new comment:
I'll bring back my story ideas and complete them and publish them as books, it'll let me pretend that I have an active imagination as a writer and that I just got lucky with the lottery and used it to put money in tech that fascinated me and just was good at imagining tech.
I'll do a fast forward course of comp-sci to present RISC-V based on that and use common terminology to explain it as much as possible.

Future weed.

That's true, a big sack of super dank 30% seeds would go a long way. Funny thing is we'd be just as happy with some of those old strains, so you could win again by freezing seeds from true NL5, Skunk #1 and so on in 1999.

Do the whole Back to the Future thing and take back a list of lottery winnings, stock picks, etc. Just keep slyly moving things around at the proper times and you'd have no trouble becoming the next Bezos.

I sense satire but I'm also not sure.
Who hurt you?

Not a bottle of Vodka and Champagne, I mixed both of those to excess the last time around - never again

How the fuck do you take your self's place? You're either a your current age trying to identify as a baby or you're a baby which doesn't have the mental capacity to remember having the historical info.

I have some crazy news for you. Not everyone is 21. Believe it or not, but there are people who are older than that (I'm one of them! Boo!)
- I misread OP. I was under the impression that you reset as a 21 yo
It's simple. Say for instance you were 30 years old in 1999. You would just slot into your 30-year-old self and have an opportunity to make new decisions loaded with information about a highly likely future.
However, if you were a baby in 1999, you probably would not want to take your own life over so you would choose the new body option, and lead a completely new life separate from your old one.
- But how is there not a 24 year difference and 2 of you? Makes 0 sense
