Go to college undeclared. Many students do that, they take a large variety of classes, see what subject they like best, and then make that their major.
Also, different majors will open you up for a lot of things. Don't lock yourself into anything really specific, for example, instead of opting for "cellular and molecular biology", choose, instead, biology so even though you study one subject, your not locking yourself into something too permanent.
