No matter what everyone else tells you, your passion for videogames is absolutely beautiful. Don't let them put you down. Your parents wouldn't complain if you spent 6 hours a day writing, reading books, studying or exercising. Why aren't they cheering you on? Because they're prejudiced, nothing more.
Don't get your hopes up about a political party or candidate. They'll let you down, like they always do.
I know you're afraid of metal music right now because of the people bullying you having Metallica and Napalm Death t-shirts, but you really should listen to some, it's really fantastic.
Don't be ashamed of liking The Powerpuff Girls. A few years from now, you'll be liking a show about ponies with millions of other adult guys. Gender stereotypes SUCK.
Most people respect the guys who pick on you. You're afraid of them. That doesn't mean people need to fear you in order to respect you. Smile and be yourself. Way less tiring and way more satisfying.
Yeah, that girl is very, very pretty, but stalking is creepy. Stop it. She's not worth it anyway.
Don't go to college just because your parents tell you to. If you go, try going to something you like. How about game design?

Yeah, that was more than one piece of advice. Heck, if I could contact my teenage self, I would probably write a 3-page letter.
