Forget about where you want to be and go out and build stuff. Dodgeball came from being bored at work... things happen because you make them happen. Stop sketching, and start building.

I keep a notebook in my pocket, and I write down all the stuff we could ever do with Foursquare.

Do what you love and the rest will come.

Build something that fixes something people are having a problem with, and you're lined up for great things.

I'm still a really shitty programmer, but I know enough to hack a prototype together.

Stop sketching and start building.

People can copy what you've done, but they can't copy what you still want to do.
