"We believe in the power of science."

"There is no substitute for hard work."

"We are building tools that empower people."

"The future will be shaped by those with vision."

"We should always be learning."

"Technology companies have a responsibility to society."

"The Internet is the first thing that humanity has built that humanity doesn't understand, the largest experiment in anarchy that we have ever had."

"We are not really pre-optimizing. We are thinking ahead to the future and trying to build something that will scale."

"Everyone has the potential to change the world, you just need to believe in yourself."

"The future is bright for those who believe in the power of information."

"We are in the business of organizing information, and the world needs that badly."

"I would rather be leading a company that is doing something really meaningful."

"Technology is best when it brings people together."

"We want to make sure the things we build are things that people really need and want."

"The amazing thing about Google is that by just sitting in front of the computer and using it, we sussed out an awful lot."

"I think it's important to have a way into the future that doesn't just involve technology."

"You can't have really good software without a passionate software engineer."
