As others have stated: lose the 60 hour work week. That was insane when you were young and crazier as you get older. In 20 years the only people who remember your effort for your boss, are your children because you were never there for them.

An advice from my father in law that always stayed with me: if you can, try to find a job far enough to enable you to flip the mental switch from employee to house father and back, but nearby enough to not waste time commuting. He used to need 30 minutes for that. I need a 15 minute bicycle ride.

Also: long walks, running in the weekends and a few beers every night. Not proud of the latter.
