I don't know what I wanna be. I'm gonna be a junior?

It's not such a big tragedy to not know what you want to be. I know people who already started college and still haven't figured it out. Taking a variety of classes on different subjects is a good idea to figure out what you like and it can help you find a specific job. When you go to the Universtiy you will start out by taking general classes and maybe you'll figure out what you want to do as you take those classes and explore different majors that are offered at the Univerity. Volunteering at different jobs is also good to see what you like to do.
