Ask yourself this question: "Do I like what I do for a living?" If you answered "no", what are you doing about it? Maybe you have a "good" job, but it's not very rewarding to you personally. Maybe you have a job with good pay, but bad hours or worse - a job with good hours, but bad pay. Perhaps you've just done your job for too many years, or are excited to work in some of the new careers that just weren't available when you finished school.
