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

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 always live in an uncertain world. What is certain is that the United States will go forward over time.

Only time will tell if it was time well-spent.

Time perfects all living beings as well as kills them; it alone is awake when all others are asleep. Time is insurmountable.

Don't waste your time away thinkin' 'bout yesterday's blues.
