Don't go to law school, I guess:
Lawyers are 3.6 times more likely to be depressed than members of other professions, and it's not just because their jobs are more stressful. For most people, job stress has little effect on happiness unless it is accompanied by a lack of control (lawyers, of course, have clients to listen to) or involves taking something away from somebody else (a common feature of the legal system).
Update: This comes from a New York magazine article collating lots of new data on happiness into a series of digestible recommendations. Worth a read, if only for entertainment value. Knowing that my choices and decision making processes appear to be mood-killers doesn't make me very, er, happy. Reading lists, however, does.
