You could join the ranks of the academics and consultants who specialize in organizational behavior. A lot of this work is in the area of motivation, creativity mgmt, leadership, human resources issues, etc. There are lots of psychologist and business types who do this kind of thing and I don't think an MD would necessarily add anything; however, it would be an easy and perhaps interesting transition. The questions in this area are intersting and important, but the research is pretty shoddy and the questions are unanswerable (observational studies only --with a low n).
