Don't get me wrong im usually bored when I'm out of work. But that's more because when I'm not working I also don't have money to do other meaningful things.
Well, at least learning languages is both cheap and not very time consuming ( although more time is always better ). But in terms of years it's still a long time.
IME not working and working in the range of 20, 40, and 60 hour weeks, around 35-40 is the sweet spot for me.
I'd be happy working (making profit for someone else, and getting a tiny portion of it) 0 hours a day.
I've projects, ideas, experiments, and entertainment I would much rather be doing than 40h/week . I want live and do, not toil for some indifferent capitalist.
You are using the term "work" differently than EVERYONE else here.
