A man who dares to waste one hour of time has not discovered the value of life.

My favorite things in life don't cost any money. It's really clear that the most precious resource we all have is time.

You've gotta keep control of your time, and you can't unless you say no. You can't let people set your agenda in life.

Of all the inventions of humans, the computer is going to rank near or at the top as history unfolds and we look back. It is the most awesome tool that we have ever invented. I feel incredibly lucky to be at exactly the right place in Silicon Valley, at exactly the right time, historically, where this invention has taken form.

We all have a short period of time on this earth-We probably only have the opportunity to do a few things really great and do them well. None of us has any idea how long we're going to be here nor do I, but my feeling is I've got to accomplish a lot of these things while I'm young.

Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time and opportunities.
