Sometimes you have to look at a situation differently from what you usually do. You have to watch each person and see how they act. I have to listen to each patient, and not just to their words. The patient has something to tell you, but won't or will miss something if he's nervous and scared. Real medicine is a healing art as much as, if not more, as it is a hard science.
Intuition plays a lot larger role than most think.
There's a lot more creativity and imagination that most people think. And that can sometimes be more important than information. Sometimes it's just trial and error groping, and guessing. Medicine is about people, not just pills. Just because you know medicine doesn't mean you're good at it.
