College is supposed to be the best four years anyone experiences. Anything can happen. It's the transition into becoming more of an adult and taking more responsibility. It's the time to let loose. It's the time to figure out what you want to do with your life. It's the time for just about anything.
A student can start their college career as a biology major and finish their college career as a business major. It's the time to try out some classes, realize you actually hate it, decide this major might not be for you and try a whole new path. This is the time to understand what you want to do with your life (or at least have a general idea).
It's the time to try out drinking for the first time. You have one bad night and realize that drinking may not be for you. You try out the party scene. Still not for you. Or it may be. Everyone comes into college wanting to try out these scenes and see if they enjoy it. Many do. Many don't. Everyone is different, but don't knock it until you try it.
New people are all around you. New men. New women. Let loose and try to understand what you're looking for relationship wise. Maybe you thought one way your entire life, get to college and try out something new, realize you feel more comfortable, and you start your lifestyle feeling more you than ever. You never know until you give it a try.
Maybe the college you decide in general may not be what you thought it was. You now know because you were able to experience it yourself. You have an idea of what you're looking for now. You may have gone to a big school and decide that a small school would be best. Tried out a college in the city? A small town may be more comfortable for you. There is nothing wrong with changing schools to better fit your need.
You may have signed on to take this big internship and you realize a month later that you don't want to do this for a career. You would have never known unless you tried it out first. If you denied it, you would have wondered if that was the best decision and you will always wonder. Now you have an idea of what you don't want to do with your life. You can use process of elimination.
College is the time to figure yourself out before you officially step into adulthood. This is the time to do what is best for you. This is the time to figure out what makes you truly happy.
