Couldn't he just give all the money to charity and go back to his previous lifestyle if on the whole it was better than this one? I mean if the money is the problem and he doesn't feel it can be fixed by throwing money at it, then why not donate it all to charity and start work on a new game while working at Denny's?
See that is the problem I have when people talk about coming into money ruining their life. I don't think I've ever seen any of them get rid of the money to return their life to what it was, at least not intentionally.
Because that's not how it works. The money in this situation fundamentally altered his social existence. His friends from Mojang are pissed because he gave them proportionally small bonuses rather than set them up for life. He then moved to the other side of the planet to live in a castle on a hill in a city obsessed with wealth and fame. Massive change plus alienation from everything he's ever known in terms of a home and his friends/family is going to take a toll. You can't really stuff that genie back in the bottle, and he didn't really have a choice in letting it out, because the sale of Mojang was international business news.
