We have always tried to concentrate on the long term, and to place bets on technology we believe will have a significant impact over time. It's hard to imagine now, but when we started Google most people thought search was a solved problem and that there was no money to be made apart from some banner advertising. We felt the exact opposite: that search quality was very poor, and that awesome user experiences would clearly make money.

Sergey and I founded Google because we're super optimisitc about the potential for technology to make the world a better place. Think about how many people are underserved by transportation today, like those with disabilities, and how self driving cars will transform their lives. Or the wasted time you sit in your car every day commuting to and from work. Or the deaths and injuries that could be avoided.

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.

Always work hard on something uncomfortably exciting!

My job as a leader is to make sure everybody in the company has great opportunities, and that they feel they're having a meaningful impact and are contributing to the good of society. As a world, we're doing a better job of that. My goal is for Google to lead, not follow that.

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

Every story I read about Google is about us vs some other company, or something else, and I really don't find that interesting. We should be building great things that don't exist. Being negative is not how we make progress.
