Spandrel's right. Start working out. Buy a set of weights and start using them. The satisfaction from seeing your biceps literally grow, the definition in your shoulders and the emergence of abs is truly amazing.
I don't know what you play your video games on, I'm big on VG's myself, but I'm not one of these folks who obsess over them. The key is a healthy balance. If you've got an Xbox or a PS3, take your games and put them under your bed, in your wardrobe wherever. Then take the power cables and put them somewhere else. If you're a PC gamer unistall the games, keeping backups of the local files or if you're on STEAM change your goddamn password to something random and not easily memorable, write it down. Trust me, when you're truly addicted to something that first clean day is brilliant.
If you're still at school focus your time on studies. Master something to university level if you can. If not, find something you want to learn and dedicate yourself to it.
Got a camera? Get outside, take some photo's and edit them. 'Bitches' love a guy who's good with a camera.
Best of luck bro. I know that if you truly believe you can kick something you can. I've watched people who've used Smack for the time I've been alive (~20 years) kick it.
As a side note: Part of a strong inner game is believing that with self determination anything is possible. Let this be fuel to your personal fire.
