Don't let other people distract what you're doing. There's always haters.

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 used to snowboard 30 days a year. Now its down to eight.

Stop sketching and start building.

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

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.

Hire the best people you can find. This was kind of easy in the early days of foursquare - we hired our friends who were really passionate about the stuff they were building. We have a superstar team not just because their resumes are so strong, but because they've been passionate, thinking about and tinkering in this space forever. Those are the people you want to surround yourself with.
