Why Do We Push Ourselves?

Hey guys,
Today I'd like to talk about a few things that ... worry me? These are things like conforming, make-up and pushing ourselves out of our boundaries.
Firstly, I'd like to talk about me. I'm normally a very quite, reserved, shy person and I'm not one for going out, make-up, all of that. However; since being at University I've been thrust into the "go out, go crazy, go hard or go home lifestyle. Is this something that appeals to me, hardly. But yet I still persist on doing it? But why? I was in fact meant to go out tonight, but after an hour of failing to do my make-up, ripping my tights, picking out which dress. I began to think, who is this really for? It's evidently not for myself. My eyes are sore, my head aches and I'm hungry; having not eaten. So why do we keep trying to impress?
I know that some people enjoy it, but I'm claustrophobic, I hate loud music and I find it awkward to socialise with anyone in a club. Having people scream in my ears doesn't appeal and staying out till 2am is even worse. I know some people want to live whilst their young, go crazy, go to Magaluf. But in a way I don't want to be like that. I don't want to have my "moment of rebellion" for me I know that I'll never go to Magaluf (if I were to go it would be only to merely pass through). I know that I'll never stay out to 6am. Or even get drunk again. Yet why do people like this way of life? It's something that really baffles me.
I like to study hard and reward myself by socialising in quite pubs and such a like. I know that people want to make friends and this can all be "accomplished" through clubbing. But for me, meeting someone my own age at work, at a pub, at a quiet social event seems much more appealing.
Enough of me.
I just fail to understand the sole purpose, I get the fun aspect and the let's go crazy. I know that so please don't correct me on the let's go crazy. Yet, as a human being I feel that my heads firmly screwed on, I'm not a prude, I just have other ways of enjoying myself. I don't like to be out of my comfort zone and today I've realised that.
No person should conform to what another person desires.
What I'm trying to say is, do what you feel comfortable with. I know that their is a lot of other people like me; who think that it will be fun, exciting and really we just need to sit back and think. Is this really what I want?
Have a think...
Love,
