The biggest mistake that I made was not anticipating the rise of the social networking phenomenon.

Even though Google may do very well, there will always be an alternative to what Google is doing, and people will always have the free choice... because there's no way for us to prevent them from exercising that choice. That is one of the key aspects of why the Internet has been so successful. No technologies can dominate.

The funny thing about advertising is that it's not a zero-sum game... Historically, in the digital ad world, pie has gotten larger and it's possible for everyone to win, and it's perfectly possible that will continue to be true for quite some time.

Android is ahead of the iPhone now.

In a networked world, trust is the most important currency.

I still believe that sitting down and reading a book is the best way to really learn something.

I'm able to bring business expertise but, more importantly, operating experience. The people here at Google are young. Every day there are lots of new challenges. I keep things focused. The speech I give everyday is: "This is what we do. Is what you are doing consistent with that, and does it change the world?"
