Colleges have career counseling departments. They can offer you standardized tests to see where your interests lie; they can also help you think of alternatives that interest you. (If for some reason your college doesn’t have one, you may be able to use similar services at another local college. You can also look for career counseling services offered independently in a nearby city.)
