The Johnson O’Connor Research Foundation (see <http://www.jocrf.org/home> http://www.jocrf.org/home>) has found that there are several different “aptitudes”, and you need to be really, really good in at least three of them before you are likely to be successful and happy as a surgeon. They’ve got longitudinal studies over several decades with strong statistical methods. If you are ever between jobs, or wondering what things you could be really good at or what careers might be a good choice for you, I highly recommend signing to take their extensive testing procedures, and then following up with them over the decades.
