I pace myself by taking a week-long vacation every four months.

I took a computer-science course to fill a prerequisite at Stanford, and I realized that every day was a new problem, and every day you got to think about how to solve something new, how to reason through something new, how to develop an algorithm to solve for something you hadn't worked on before.

It makes you feel like you're on vacation. It's the kind of drink that should have an umbrella sticking out of it. It tastes great in the winter months.

Before Google, I spent the summer building a program that would look at what websites you would go to and what websites other people would go to - and built a collaborative filtering program that helped you find related sites to look at.

I think Google should be like a Swiss Army knife: clean, simple, the tool you want to take everywhere.

You can't have everything you want, but you can have the things that really matter to you.
