Has it been a while since you held a full-time job because you took time off to raise kids? Or maybe you feel you've been on the wrong career path for some time but quitting right now seems too risky. Or perhaps you don't want to leave your job, but your prospects for advancement are limited and you just feel stuck.
Sam W (not his real name) hadn't been happy at his job at a New York area corporation for several years, even though he was doing very well. His bosses kept promoting him -- and that was the issue. With every promotion came more responsibility and more money, but less and less joy. Finally last spring, with no other job in hand, he announced his resignation. He's now taking classes at a local university, actively looking for teaching positions, and is much happier.
