I have over 2 million followers now on Google Plus.

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.

We should be building great things that don't exist.

I remember turning in my first assignment in elementary school using the computer and the teachers were kind of confused that I had printed it.

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.

You never lose a dream, it just incubates as a hobby.

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.
