Most of us carry at least one device, all the time, every day. In fact many of us would feel naked without our smartphone. It's hardly surprising mobile search queries -- and mobile commerce -- are growing dramatically across the world.

Almost everyone who has had an idea that's somewhat revolutionary or wildly successful was first told they're insane.

If you can run the company a bit more collaboratively, you get a better result, because you have more bandwidth and checking and balancing going on.

We believe strongly that in the long term, we will be better served -- as shareholders and in all other ways -- by a company that does good things for the world even if we forgo some short term gains. This is an important aspect of our culture and is broadly shared within the company.

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

Computing is kind of a mess. Your computer doesn't know where you are. It doesn't know what you're doing. It doesn't know what you know.

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

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.

Optimism is important. You have to be a little silly about the goals you are going to set. You should try to do things that most people would not do.

My grandfather was an autoworker, and I have a weapon he manufactured to protect himself from the company that he would carry to work. It's a big iron pipe with a hunk of lead on the head. I think about how far we've come as companies from those days, where workers had to protect themselves from the company.

The web is a vast collection of completely uncontrolled heterogeneous documents.

Google will fulfill its mission only when its search engine is AI-complete. You guys know what that means? That's artificial intelligence.

I can't really comment on rumors.

If you look at the people who have high impact, they have pretty general knowledge. They don't have a really narrowly focused education.

People are starving in the world, not because we don't have enough food, but because we're not organized. And computers are part of that.

Over time, our emerging high-usage products will likely generate significant new revenue streams for Google as well as for our partners, just as search does today.

Excellence matters, and technology advances so fast that the potential for improvement is tremendous. So, since becoming CEO again, I've pushed hard to increase our velocity, improve our execution, and focus on the big bets that will make a difference in the world.

We're at maybe 1% of what is possible. Despite the faster change, we're still moving slow relative to the opportunities we have. I think a lot of that is because of the negativity... Every story I read is Google vs someone else. That's boring. We should be focusing on building the things that don't exist.

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.

You need to invent things and you need to get them to people. You need to commercialize those inventions. Obviously, the best way we've come up with doing that is through companies.
