Future Plans?

I have been asked this question a lot this school year. What are my plans for the future? It's hard to believe that in a couple of years I will be in college. The question is...for what? So many things interest me that I can't make heads or tails of which one to choose. In my junior year of high school, I have to take a career planning class as an elective. I guess I have six months to come up with something.
