I'm totally with TNT on this one. I am now only 1 year away from applying to medical school. I know a lot now about the body and how it works, more than a lot of people, but do I know it all, no, hell no, not even remotely close. 3 years of college is a lot, but I still am looking down the barrel of 5 more. I will learn a lot in those 5 upcoming years. Overall, a career in medicine is a constant learning process, new innovations, new techniques, and tons of different perspectives from various fields of medicine are found and offered everyday. There's never an end to what you can learn as a physician. To act like you know it all at this stage in your career is a mistake, and sadly, someone could get hurt for your bullheadedness. It's a shame that some day you'll be called doctor.
