I also think this is just as important as the money/time issue. Ego and vanity are huge factors. Ask any class of first year medical students what they want to be, not a single one will have had any real experience with ANY type of medicine, and all will answer either, plastics, ent, derm, ortho, or some nonsense about interventional pediatric neuro/cardio surg. First week of classes I had a girl tell me, with a straight face, that she wanted to become triple board certified in pediatric CT surg, OB-gyn, and pediatric neurology, then she wanted to move to Africa to set up a free clinic to remove brain tumors, fix kids hearts, AND deliver children. You could see her face just glow with pride as she waited for me to tell her how amazing that her dream was. I told her I wanted to open up abortion clinics on every street in inner cities and she has yet to say a word to me since. I thought she was joking, but it turns out she was no crazier than half my class. Word on the street is that she made a B average her first semester, which would put her about middle of the class, but she was so upset that she started seeing a psych and is now on ADD meds. Im telling you, you couldn't make this stuff up if you tried.
