Point 6: Don’t worry about your unread messages. If a message is important, someone will ask you about it. If it wasn’t, you won’t.
I've done this plenty of times. Get back from holiday and I just mark everything as read. If something was important they'll email again. I've told people and they thought I was crazy but it's never not worked.
Ain't no way a 2 week old unanswered email is still relevant today.
Everyone is having a bad time, in different ways. It's easy to notice things you personally relate to, and equally easy to overlook the many, many things that don't resonate with you.
I feel the same about some of the work I need to do for my job... Start a job, can't complete it for X reason, leave it pending, never want to work on it ever again...
I hate when I glance at it, resolve to take care of it later, and then the mere act of doing so marks the matter as resolved in my brain and it's just gone forever.
"I remember that I had remembered that I needed to answer it, but I don't remember actually doing it. In the case I didn't - now it's too late anyway and doing it now would be awkward."
