Some people go to college because they dont know what to do, some go to college because its only a pathway into their profession, some people go to college because they want to experience the student lifestyle, some people go to college because they want to learn in a structured environment, and most go to college because it is a proven pathway to a decent job and a better future.
In my opinion college is not a waste of time and money, you will gain knowledge and knowledge is the key to everything.
