Not to be downer, but I think the perception of uni life is overhyped and exaggerated. I think this is because usually you only really hear about the really good stuff, positive experiences. People who are naturally outgoing and gone clubbing every other night, are usually the more vocal ones in telling others of their experiences - twitter feeds, ''OMG COMPLETED WASTED 3 DAYZZ IN A ROW'' etc etc, you get the picture.
The quieter students, the ones who probably only go out once every week or two and the ones who don't even drink, they tend to be less vocal, they tend to just get on with their own lives without much bother. Don't get me wrong though, for a lot of people, uni is the best time ever, but what about those who had a much milder time? You probably won't have heard from them, they're not going to be on twitter or facebook posting pictures of themselves having a quiet netflix session in their room on a Thursday night. .
