If Google teaches you anything, it's that small ideas can be big.

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.

Don't take too much advice.

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.

What you collect says so much about who you are.

I want Pinterest to be human. The Internet's still so abstract... To me, boards are a very human way of looking at the world.

I think the thing that I've learned is that really great people, they actually want to work on hard problems.
