This. I was in the exact same position myself. Built a multi-million dollar affiliate company 4 yrs ago, checked out mentally a year and half ago, then finally resigned from my daily duties late last year, staying on only as an adviser.
Still running campaigns on the side to keep me busy while I figure out what the hell I want to do with my life.
Leaning towards starting a wild animal control & wildlife management business. Would be taking a HUGE paycut but at the end of the day I'm still a redneck and hunting & chasing animals around is something I thoroughly enjoy doing.
Everyone thinks I'm crazy but they can all lick my sweaty nuts. I'm sick and tired of staring at computers all day.
