I use Pinterest for everything. Book collections, trips, hobbies. It’s all there. I planned my wedding on it. When I had a kid, I planned all his stuff on it. So it was nice to discover that I wasn’t the only one.

The companies that I really admire the most are the ones that have a deep visceral understanding of why people use their service, and they figure out ways of making money that are completely consistent with how people are feeling and what they are doing at the time.

There's a lot of pressure to look like the last company that was successful.

Most people generalize whatever they did, and say that was the strategy that made it work.

Don't take too much advice. Most people who have a lot of advice to give ~ with a few exceptions ~ generalize whatever they did. Don't over-analyze everything. I myself have been guilty of over-thinking problems. Just build things and find out if they work.

I look around my neighborhood, and I see people hailing a cab or ordering their food and then paying for it all with their phone. I've read about that stuff for a really long time, and now it's starting to become commonplace.

I used to wake up and look at our analytics and think, “What if yesterday was the last day anyone used Pinterest?” Like, everyone collectively decided, “We’re done!” Over time I got more confidence.
