Good stuff, keep it up!
When I was your age, I was making $200/mth through hard labor, and it was 10 times higher than an average student :-)
Since you seem inclined on entrepreneurship, I would highly recommend that you tackle negotiation skills, since those tend to define the financial outcome of idea+implementation. You can start with Jim Camp book "Start with NO...The Negotiating Tools that the Pros Don't Want You to Know" and reading about Richard Branson, and go from there.
Good luck.
