Just don't give a fuck.
Hang out with whoever you want, if you like spending time with them. If not, politely avoid them. Never force yourself to be around someone just because it will give you status. It's what every loser does. But rep isn't anything; you can spend your time better than kissing someone's ass.
Do whatever you want to do. Use your current talents and skills to build a name and identity you want to. If you play sports, show it. If you play guitar, form a band. If you dance, dance. Do whatever you enjoy the most (sarging doesn't count

).
Be who you are. Ultimately, be who you are. Yes, make friends with anyone. Everyone has something to offer you, and there's no point in making enemies just for the heck of it.
You have the power now, they don't know you. Do what you want to do. Oh and one thing. Don't worry, you'll survive and make it through those first few months. Just relax, it's never as bad as it looks. I was there too. It's not that bad. Chill out.
