I'm 37 and absolutely cannot imagine myself working for the man for another 30+ years. I can't seem to last more than 2-3 years at any one job before becoming bored out of my skull. My present position, which I've been at for ~6 months, already has me mired deep in ennui (It was utterly unchallenging from day 1 - but the pay is great).

I want nothing more than to quit and strike out on my own, but financial obligations (kids, mortgage, etc.) are holding me back. My wife doesn't understand why I make a comfortable six-figure salary but am so discontented with my career. Maybe I feel like I'm running out of time?
