How can I get into MIT?

Next year I will be starting High School and my goal is to get into Massachusetts Institute of Technology. For classes I am taking accelerated biology and geometry, plus all honors everything else. I will also be on the varsity swim team and I plan on joining Key Club, Art Club, Students Towards A Greener Earth, and Best Buddies. Plus, I will be a member of my schools alcohol awareness group. How can I make sure that I get into MIT?
