I just loved everything about this show. It was way more erudite than it had any business being, ESPECIALLY considering the vapid television offerings of its time.
Don't sweat it. I used to feel the same way. Then, somewhere in my 50s, I realized that I actually had already been doing what I wanted: everything. "Jack of all trades, master of none".
I did strive toward mastery of most things I tried that I liked enough to stick with for awhile. I like to think that I generally achieved competency, but I know that I had a few bosses and coworkers who would dispute that. :)
Learning new things and having new experiences is priceless. If you can find that within a particular career, that's fantastic, but it's not the only approach.
