Mobile is the future, and there's no such thing as communication overload.

It's a mistake to predict the size of markets that are so new. This model has shown no signs of slowing down. So we are going to get as much of it as we possibly can, and when we get close to that we'll figure out other problems.

The thing that people seem to miss about not just Google, but also our competitors, Yahoo, eBay and so forth, is that there's an awful lot of communities that have never been served by traditional media.

The Internet is really about highly specialized information, highly specialized targeting.

To me, what you want to do is find a way to let this play out between the virtual world and the physical world...Ultimately, I think society will get there. It will be messy, but we'll get there.

Find a way to say yes to things. Say yes to invitations to a new country, say yes to meet new friends, say yes to learning a new language, picking up a new sport. Yes is how you get your first job, and your next job, and your spouse, and even your kids. Even if it's a bit edgy, a bit out of your comfort zone, saying yes means that you will do something new, meet someone new, and make a difference in your life. Yes lets you stand out in a crowd, be the optimist, to stay positive, be the one everyone comes to. Yes is what keeps us all young.

Around 400 million people in the last year got a smartphone. If you think that’s a big deal, imagine the impact on that person in the developing world.
