I took a surfing lesson in Hawaii last week from a guy who has a degree from Florida State (business, if I'm not mistaken, but I'm also not positive).
After graduating, he realized that he'd rather live in Hawaii and spend his days in the ocean than sitting at a desk. Yes, he could earn more money...but he's very happy doing what he does. He keeps in touch with friends that he graduated with, and while many of them would like to switch places with him, he says he wouldn't switch places with any.
Of course, they may be setting themselves up for a better retirement, etc. But he has realized that a simple life that makes him happy is what he wants. Good on him.
