I like the person that I am now and wonder if changing something would have made me a different person. The things I'd like to change have more to do with my family - I'd like to make my father not a sociopath - things I couldn't change, than anything to do with my own life.

Job-wise I think I would have been happier going into the Coast Guard rather than being a doctor. But I'm looking from the outside, so who knows?
