What would you tell future doctors?

I have been asked to be a speaker at a Future Physicians club meeting on a university campus. I have been a nurse for 26 years, so I do have some things to say. But I would love any nuggets of wisdom you have for these young people. I was going to start by reminding them that they know more than we do- their education is more extensive- but we know the patient. We spend hours rather than minutes with their patients. So our assessments are significant.
