I've always told myself that if I'm ever laid off in my 20s or early 30s (at the latest) and I don't have kids yet or a mortgage then I'll become a dentist. It's something I've always wanted to do, but I can't really justify giving up a great job with a great income to go back to school. But should I find myself unexpectedly without said job, then maybe I just would, unless other obligations prevent it. My point is simply -- is there something for you which plays the equivalent role of dentistry? If so, maybe this is your opportunity to pursue it without feeling guilty about giving up a great job. If not, then I recommend following all the other advice here.
