People in your late 30's and tired of working... what's next?

So let's say you're married - no kids to worry about and you're tired of the whole corporate world gamut. Your patience is too thin to deal with the know it all college grads who had Zero work experience, huge egos and zero emotional/self awareness. You're still young but mentally you're 10 years older than your biological age. What do you do with life? It's kinda too early to fully retire but if you didn't work, things would be a little tight on the budget but HH income will be around $100k with out your contribution... would you quit? No debts either but you've been busting your butt working 70 hours a week for the past 17 years of your life...I'm talking work-a-holic burnt out beyond belief.
