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

I thought Google was the coolest place. People there were so smart and they were all doing these really interesting things. I just felt really lucky to be a part of it even in a small way.

At a small company, so much of the trick is focus. Not only can you only do a finite number of things, but you have to do them in the right order.

What you collect says so much about who you are.

I think that a lot of the most talented and driven people, they're not super deterred by failure. So if you put out a really big challenge, I think they get reality excited by that - they say, 'Hey, why not, let's go give it a shot, and if we fall short on that, at least we took a shot at doing something really important and meaningful.'

When Pinterest works well, it helps you find things that are meaningful to you. We want to build a system that helps you do that.
