Foursquare makes maps special. We take maps that are blank and put dots on them to help you figure out what to do.

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

What we're starting to see is that the best apps tend to be the simplest, the easiest to use and the fastest to use.

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 learned early on not to feel badly about reaching out for help, and not to feel embarrassed about saying that you're in over your head.

Don't let people tell you your ideas won't work. If you're passionate about an idea that's stuck in your head, find a way to build it so you can prove to yourself that it doesn't work.

Stop sketching and start building.
