I used to be friends with a surgeon and based on what he told me you need to have a certain level of hubris or arrogance to do that job. He told me of situations during surgery where he had to make a quick decision that could have either severely harmed the patient or led to success. He also knew cases where he had made the wrong decision. It requires a certain kind of person to take that responsibility and live with it.
