"But there is one in filmmaking," I thought. That's it! I was lost, but now I was found. I was declared!
15 years later, I think of all my friends who so confidently began college with their majors declared. Of those who went around asking, "What's your major?" very few are working in their chosen jobs. I didn't end up a filmmaker. And some days I still feel "undeclared".
It really doesn't matter what you major in, as long as you have a prosperous university experience. Involve yourself in those things that interest you and enjoy learning about the world. There is plenty of time to decide what you will do with the rest of your life.
