You don't have to settle for shitty bosses. You are allowed to have as much free time as you want and afford, and if I want to spend some of it watching TV, then pretentious twits can kiss my ass.
What I did wish I knew was that the most precious part of youth is in fact the social, romantic, and sexual opportunities. If I would have known then what I know now: that all my appeal to women would somehow vanish in my thirties and that I'd experience nothing but romantic rejection for years, I would have planned my life extremely differently. Anyone who says you can take for granted that men have it easier in their thirties is full of shit.
The single most important thing I should have done in youth would have been to optimize my chances for sexual and romantic relationships with a chance to last a lifetime. Having this or not (not money) is the difference between years of relative bliss and years of feeling that life is basically fucking pointless.
Yes I'm angry.
