I want to go to Harvard, is it possible?

I am 13 right now and I am VERY interested in my education. I am certified gifted (i know it does not mean anything) and i am going out-of-county for a higher education (for the International baccalaureate program) is there anything that can help me get into Harvard (or maybe some guidelines that I should fallow during High School)? My goal is to be a lawyer later in life.
