If you can manage it, cut your expenses to the bone (seriously, be ruthless, you'll appreciate it later) and live on cash for a few months. You'd be surprised with how long you can live happily without most of the things we accept as normal these days.
Just take a sabbatical for a little while. It has always helped me clear my mind and figure out what my priorities are. I once thought I was going to quite programming completely, but a 2 month sabbatical made me realize that I just hated "corporate culture". Now, I freelance and make art about "corporate cargo-cultism".
Use the time to try out things you've always said you wanted to do but never seemed to be able to get around to it. I made t-shirts for a while. I learned there ain't a lot of money in making t-shirts. No point in keeping that dream around, nagging at me in the back of my head. Turned out all I really wanted was a custom wardrobe. Got that, done, next.
I made props for a while. Small, independent film productions. Museums. I didn't plan it, but because of my sabbatical and my lack of plans (The Way of No Way, as Bruce Lee would call it), I was prepared to pursue an opportunity that came my way. It was a ton of fun. There is potential there, but I lack the knowledge on how to develop the contacts necessary to make it a sustainable business.
Basically, find yourself and learn what you like to do and what you don't like to do. They don't teach you that in college. Then, when you're ready to jump back in, don't take the first thing that comes along. Shop around your choices.
