Also, students go to colleges and universities to have new experiences. This often means having the opportunity to meet people different from those in their hometowns. For most students, going to college is the first time they've been away from home by themselves. In additions, this is the first time they've had to make decisions on their own. Making these decisions increases their knowledge of themselves.
Besides looking for self-knowledge, people also attend a university or college to expand their knowledge in subjects they find interesting. For many, this will be their last chance for a long time to learn about something that doesn't relate to their career.
I would recommend that people not be so focused on a career. They should go to college to have new experiences and learn about themselves and the world they live in.
