If we were motivated by money, we would have sold the company a long time ago and ended up on a beach.

We should be building great things that don't exist.

For a lot of companies, it's useful for them to feel like they have an obvious competitor and to rally around that. I personally believe it's better to shoot higher. You don't want to be looking at your competitors. You want to be looking at what's possible and how to make the world better.

Most of us carry at least one device, all the time, every day. In fact many of us would feel naked without our smartphone. It's hardly surprising mobile search queries - and mobile commerce - are growing dramatically across the world.

It really matters whether people are working on generating clean energy or improving transportation or making the Internet work better and all those things. And small groups of people can have a really huge impact.

Technology should do the hard work, so you can get on and live your life. We're only at one percent of what's possible, and we're moving slow relative to the opportunity we have.

For me, privacy and security are really important. We think about it in terms of both: You can't have privacy without security.
