How can i get into Harvard?

I'm very smart. Not outrageously though, and I'm starting 8th grade I am very ambitious and planned out my whole life. And one thing I want to do is go to Harvard to study law to become a lawyer. So thinking this early I'm wondering what I need to do for the next about 5 years. What classes, g.p.a, recommendations from who? I live in Florida and already have the pre-paid college but what can I do? I could still get in if I was smart and since my family has a good amount of money. Could I even try to get in if I have pre-paid? If I had any chance I would take it. I plan on working very hard on my school work now. I also play soccer as mvp. And volleyball if that helps.
