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 your business is static, you're likely to have issues.

Small groups of people can have a really huge impact.

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.

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

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.

You don't need to have a 100-person company to develop that idea.
