If there's something you want to build, but the tech isn't there yet, just find the closest possible way to make it happen.

Don't let people tell you your ideas won't work.

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.

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.

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.
