Hello, seddit! I'm 22M, typing this all the way from southern Brazil, and I'm about to start a new part of my life: I just got into college.

I know, right? 22 is a little older than usual for someone to enroll in college (at least here in Brazil, it is, most people enroll at age 18). But I think it's gonna be for the best, since I'm way more mature and alive than I was a few years back.

So, in what exactly do I need help? I need help in the same way a lot of other guys here do: I am too much of an introvert and a shy person. In the last couple years, I was kinda depressed and studying too much so I could enroll in a public university, which are the best around here. Because of that, I shut myself in even more than before, and I got used to just sit in the corner, with headphones on, not giving myself the trouble to have to interact with other people. I still managed to make some new friends in this meantime, but I know I can do better than that. WAY BETTER.

Lately I've been diving into reddit and other medias looking for ways in which I can become the better possible version of me. Because right now, what I want to do is enjoy life, have a lot of hook-ups, go to parties and have fun. It's a life I want to live, but my shyness and introspectiveness are two really determining factors of who I am. I'm the kind of guy who needs a couple hours absolutely alone everyday or else I won't "recharge my batteries". But I don't want to keep on missing out fun stuff.

So, how can I improve date-wise during the next 4 (God, I hope it will be only 4) years? I now go to the campus everyday, where there are tons of hot chicks everywhere and lots of situations just waiting to happen but I have no clue where to begin. When it is appropriate to approach a girl on campus? How to stick out of the crowd in a good way? How to have confidence to approach a group of people without fearing they won't like you? We in college here are frequently going to a bar nearby, in the evening, and we always get pretty drunk. What is the best way to approach girls in that environment? How to be confident in an environment where there are hundreds of beautiful people around you?

What do you wish you knew when you got into college that you know now?

Anyway, thanks to whoever answers some of these questions, and I hope the answers are useful to others, too.
