Many people are. I know I was, years ago. You may want to start with a liberal arts program at a local community college. When you find something that interests you can major in that subject and then transfer to a four-year school.
You get the same diploma as the people that went there for all four (or more!) years, but don't waste all that money trying to figure out what you'd like to do. I tried it both ways and this is definitely the way to go, especially if you're paying for college yourself.
Good Luck.
