Most people do not realize you can major in anything and become a doctor. As long as you take the "core" courses required of most medical schools. As a matter of fact, I once read that one of the most successful majors gaining entry into medical school was music. I will warn you, once I too thought it would be easy to become a nurse and then go on to medical school, but something very strange happened to me. I fell in love with nursing. The upside of your idea is when you are a doctor, you practice just one way, your way and usually your way is the best way. after being a nurse, you get to observe a variety of doctors and objectively pick and pan what you make your own. It is often like the best of both worlds. I asked one of the physicians I worked with to write me a letter for graduate school. She told me she sent the letter in but thought I was wasting my time because I should be applying to medical school. I laughed and told her that not everyone wants to grow up to be a doctor. Whatever you decide to do, have fun and do it well. You will never regret a choice you enjoy.
