Im more of a lurker than a poster but being not much holder than you (22), and a life long entrepreneur, I'll share my advice.
I believe you already feel this way since you are posting here, but you are different then everybody else. There is nothing wrong with planning for your future -- Its good to do. When I was your age my friends played mainstream video games and I was busy maximizing my tax revenue in Simcity.
My advice, get your failures out of the way. Your parents give you a roof, and food. Spend every dollar you can on small businesses you can run, mowing lawns, pedaling candy at school, etc. If you're parents are like mine they'll tell you, you are wasting money, but the reality is you're learning a lot that will benefit your business career down the road.
As far as college, I'd recommend going for an accounting degree. Just an associates (2yr). This will give you some skills to manage your funds effectively and a decent fallback if you ever get into a tight spot and need to work a job. I would also recommend dual enrollment or some integrated high school/community college. You might be able to get your associates at the same time you graduate high school.
