Private practice--very high earning potential, no significant research obligations, get to focus almost entirely on the outcomes of my patients
Why not research or academic?
research--SUCKS (if I wanted to become a researcher I would have pursued just a PhD)
academic--don't want to worry about my underlings (med students, interns, and residents) screwing something up, because I'm the one that would get sued; pay isn't that great relative to private practice; "publish or perish" sucks ass
