Excellence matters, and technology advances so fast that the potential for improvement is tremendous.

Sergey and I founded Google because we're super optimistic about the potential for technology to make the world a better place.

We want to build technology that everybody loves using, and that affects everyone. We want to create beautiful, intuitive services and technologies that are so incredibly useful that people use them twice a day. Like they use a toothbrush. There aren't that many things people use twice a day.

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.

You can make an internet company with 10 people and it can have billions of users. It doesn't take much capital and it makes a lot of money - a really, really lot of money - so it's natural for everyone to focus on those kinds of things.

In technology, we need revolutionary change, not incremental change.
