I became a physician because I wanted to do useful work, use my intellect, use my hands, interact with people, and serve a nobler cause than just making money. Coming from a medical family, I also saw from daily observation how satisfying a career it was. I became a dermatologist after overcoming 2 obstacles to that choice: (1) I had to admit to myself that "blood and guts" medicine with people's lives on the line and middle-of-the-night crises were not for me and (2) I had to do what my father suggested.
