How do I start living my dream?

I am currently an entering junior into highschool. Looking at threads leads me to believe that this site is for already working nurses, but maybe you can help me. I've been thinking about my future alot lately and I've known for a long time that I want to become a CNM, but trying to decided what path to take from my highschool graduation has been difficult. I'm currently a straight A student and attend a private school in Wisconsin.
If any of you have any advice or encouragment as to how I might become a certified nurse-midwife it would be greatly appreciated.
