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.

The "Be good" concept also comes up when we design our products. We want them to have positive social effects.

You don't need to have a 100-person company to develop that idea.

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.

I think it is often easier to make progress on mega-ambitious dreams. I know that sounds completely nuts. But, since no one else is crazy enough to do it, you have little competition. There are so few people this crazy that I feel like I know them all by first name. They all travel as if they are pack dogs and stick to each other like glue. The best people want to work the big challenges.

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.

You're probably on the right track if you feel like a sidewalk worm during a rainstorm.
