1. Be Mark Zuckerberg: learn to program. Start with (my personal fave) Scratch, Alice, and Gamestar Mechanic. From there move on to CodeAcademy, Codea, and Game Salad.
2. Be a gamer, but with a purpose. Create a Minecraft server with your buddies. Start a clan/guild for a multiplayer game. Play quality multiplayer PC games (Blizzard, Valve).
3. Read biographies of interesting Silicon Valley entrepreneurs. Start with Steve Jobs, The Facebook Effect, and The Google Story
4. Start a Youtube channel. If you need ideas, make a screencast featuring a play-through of your favorite video game, or make a tutorial about anything you are good at. Promote it on Twitter to get views.
7. Follow the best tech writers, start with David Pogue, Walt Mossberg and TED.
