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.

Part of our brand is that we're pretty understated in what we do. If you look at other technology companies, they might preannounce things, and it will be a couple years before they really happen, and they don't happen in the way they said they would.

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

You can try to control people, or you can try to have a system that represents reality. I find that knowing what's really happening is more important than trying to control people.

It is often easier to make progress on mega-ambitious dreams. ... Since no one else is crazy enough to do it, you have little competition.

I think it is often easier to make progress on mega-ambitious dreams. I know that sounds completely nuts. But, since no one else is crazy enough to do it, you have little competition. There are so few people this crazy that I feel like I know them all by first name. They all travel as if they are pack dogs and stick to each other like glue. The best people want to work the big challenges.

We have always believed that it's possible to make money without being evil.
