Trying to be Someone Who I'm Not

The one thing that somebody once told me not to do during college was to try and be someone who I'm not; but that's exactly what I did. I'm not gonna lie; I experimented with multiple things like alcohol and smoking since I've been here and needless to say, they're not exactly things I enjoy. I try and do these things to socialize and get to know the people around me, but almost every time, I never enjoy it as much I do staying at friend's apartment playing card games or board games. I feel like I'm constantly trying to do things that I was never able to do in high school, because they were things my parents would never allow. But now I realize that there are good reasons why I didn't. It's just simply something that I, as an individual, do not do.

Now the question is if I'm going to continue doing these "bad" things and continue being somebody I'm not. Honestly, I don't really know. I don't know if people consider me as a person who parties now, or if they still have this facade of me as not a party person. I constantly got the phrase "I didn't think you were that type of person" at parties but that's exactly it: I'm not. I guess I'll just go at whatever comes to me and remember to always be responsible for my actions.
