My philosophy has and always will be, no one ever looks back and says they wish they spent more time in the office. I did the 80-100hr/wk thing, I believe that's a critical part in attaining your goals, but you can't do it forever. I got sick of the rat race, quit my job in January and spent 4-5 months home taking care of my daughter. Everyone thought I was crazy...what will you do for money, you just bought a new house, you just had a kid and have #2 on the way, blah blah blah. I wasn't going to settle for less than perfection in my next job...landed a CFO gig, with an equity stake, 7 minute commute and is a legit 35-40hr/wk job. I know for a fact it's $100k/yr less than what I could have gotten in Charlotte, but I'll be working half the hours and spending 2.5 hours/day less in the car everyday...that's worth it's weight in gold to me.
