That’s been my survival mechanism. I’d be homeless otherwise but I was able to hyperfixate on work related things and become a workaholic after failing out of school (where I couldn’t focus on courses I didn’t like).
My life/work balance has never been good, but its awesome to be fixated on the thing people pay you money to do.
If you like sound design, the sound design in Don’t Starve is by far the best ive ever heard. It is the game that convinced me of your point.
