It happens way too often, and not only to girls. I have friends who are juniors and even seniors in college and still don’t really know what they want to do. Some will probably figure it out soon enough, and some will drop out and get jobs that don’t require degrees. This is just the way of the world. I began college when I was 20, and then, I had an idea of what I wanted to do, but the degree I’m currently pursuing is a bit different from what I had in mind at the beginning.
College is very expensive, so I would advise anyone planning on getting a degree to really think about their future before making a decision.
