What are the best things I can do to try to get a scholarship to MIT?

Well, I am in 8th grade, and I am a strait A+ student. I LOVE LOVE LOVE Math, and I want to be an engineer and go to MIT. I am a girlscout, do XC and track and I'm fairly good,and I have TONS of community service hours ( churches and school from helping special needs kids and tutoring). What can I start doing now to try to work towards getting scholarships? ( well do when I get into high school)
