Do something you are good at. For instance programming. If you're a decent programmer, practice and experiment with that until you're really good at that. Read about Flow. To become a better programmer, I try to take some absurd idea I have floating around, like an automated Growl notification every time HN puts up a new tweet, and make it. I use languages like Ruby to get it done fast and to remove any stupid obstacles like linking errors and missing includes and yada-yada-yada.

In essence: get better at what you love to do.
