I like going to Burning Man, for example. That's an environment where people can try out different things. I think as technologists we should have some safe places where we can try out some new things and figure out what is the effect on society, what's the effect on people, without having to deploy kind of into the normal world.

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

If you're changing the world, you're working on important things. You're excited to get up in the morning.

Optimism is important. You have to be a little silly about the goals you are going to set. There is a phrase I learned in college called, 'having a healthy disregard for the impossible.' That is a really good phrase. You should try to do things that most people would not do.

We understand the need to balance our short- and longer-term needs because our revenue is the engine that funds all our innovation. But over time, our emerging high-usage products will likely generate significant new revenue streams for Google as well as for our partners, just as search does today.

Basically, our goal is to organize the world's information and to make it universally accessible and useful.

Lots of companies don’t succeed over time. What do they fundamentally do wrong? They usually miss the future. I try to focus on that: What is the future really going to be? And how do we create it? And how do we power our organization to really focus on that and really drive it at a high rate? When I was working on Android, I felt guilty. It wasn’t what we were working on, it was a start-up, and I felt guilty. That was stupid! It was the future.
