I asked this question 2 months ago and this is what my friend who has graduated told me;
If you're a nerd and not that great on the social side, by all means go for it. Note that being a nerd does include studying every night and then going to the movies on a saturday night as a means of justifying your study. Anyone with minimal social activity can do that. If you don't work, go to the gym, go to parties often, hang out with your friends (not at the library), grab interesting lunches, make an appearance at clubs or play sport then really you can battle it out. Otherwise you can enjoy the loneliness of doing uni work by yourself while most people are enjoying being young when they can.
When the time is right I will work off that advice. Don't be pressured by people who didn't have much of a life during high school and didn't learn anything when they switched to university.
Good luck
