Panda Bear offers some sage advice:

The first thing you need to do is to cool your jets. Medicine is a good career but it’s just a job. I’m sure you will meet some zealots who seemingly breathe, eat, and live medicine but for the most part, by the time you get into residency you will find that most of your colleagues want pretty much what other working people want, namely a useful job with good pay and decent hours. In this regard, maybe the years of working long hours for little of no pay like you’re going to do in medical school and residency beats the idealism out of people but I prefer to think it teaches them the difference between professionalism and fanaticism.
