What should i do?

Im 13 years old from kansas and im starting to give consideration to what i want to do in terms of a career. My dream is Broadway. its something ive been wanting to do for a long time. If I was going to choose this i would probably go to NYU or some other place like maybe Carnegie Mellon and get a degree in musical thatre. The problem with that is, i know that theres a very slim chance of me actually being able to make it.I was thinking maybe a minor in that and master in something else? My other option is going to KU and getting a degree in medicine. It seems like a good option since KU med school is a great school thats close to home, but im not as pionate about that as i am about performing. Could i maybe minor im performing there? What should i do? any other options are welcome too.
