Why do you feel like you HAVE to be wild, get drunk, be a "bad boy" and whatnot? So what, I'm 18 and I'm never going to drink ("oh you will eventually." NO, I won't.) You're 21, big whoop. You want to attract a girl? What do you think will attract one more? Being drunk out of your mind and throwing up on her, or drinking soda/water and having a conversation with her? You don't have to be "wild" to find someone. If anything, you'd probably end up hurting yourself. I think the best thing to say is to stop trying to be something you're so obviously not and make the most of what you have.
