I'm pretty much in the same boat. Not really set up for life, just the next decade or so. It's been more than a year since I last faced the usual "office" issues. HN, reddit, slashdot, zerohedge, my twitter feed, stocks and my hobbies keep me occupied.

In any case, it's enabled me to step out of a regimented life, I'm going back to school for a masters in an interesting field and my hopes of making a significant contribution to the world have not died down yet :). I'm on track to accomplishing some life goals. Social interaction-wise, I've taken up a few language courses and find the people I meet there a lot more interesting than those from my previous life.

All in all, I'd say not having to worrying about money ( although I didn't worry much, earlier either) or the future is very nice and definitely very good health-wise.
