Google actually relies on our users to help with our marketing. We have a very high percentage of our users who often tell others about our search engine.

I feel there’s an existential angst among young people. I didn’t have that. They see enormous mountains, where I only saw one little hill to climb.

Solving big problems is easier than solving little problems.

Obviously everyone wants to be successful, but I want to be looked back on as being very innovative, very trusted and ethical and ultimately making a big difference in the world.

My vision when we started Google 15 years ago was that eventually you wouldn't have to have a search query at all. You'd just have information come to you as you needed it. And Google Glass is now, 15 years later, sort of the first form factor that I think can deliver that vision.

We are currently not planning on conquering the world.

As we go forward, I hope we're going to continue to use technology to make really big differences in how people live and work.
