I would like to take this opportunity to make a confession:
After my third year med school general surgery rotation we had to take a skills test that involved doing a horizontal mattress suture, a vertical mattress suture, and a couple of hand-tied knots....
Not only could I not do any of that, but I started crying while attempting to tie a knot and the woman in the room who was precepting told me to stop, hugged me, and then told me to try again, sweetie.
I really feel like that should have prevented me from becoming a surgeon, not because I couldn't do it, but because i started crying and quit.
(If I pulled that now, I think I'd get kicked out of residency and they'd be right to do so.)
