Sure :D If you really have no clue what you want to do, then enroll in a college that has many, many undergrad majors to choose from. You may go in undecided, take an elective in something, and fall right in love with it.
That's how it worked for my sister, except she went to MIT. She went in wanting to be an engineer, took an elective in Geology, and threw the engineering stuff out the window. The problem she had though was that she enrolled in an engineering school, and expensive one at that ($60,000/yr), and their science program is limited. That's why she wishes she would have gone to a much larger school, where she could get a taste of everything, and dive into the one she wanted.
So don't feel bad if it seems like everyone around you has their majors figured out, because in reality, most of them are in the same boat you are.
