From that day on, if I was going somewhere, I was running.

Willpower is not virtue, but directional detonation of neural impulses.

The only thing that really matters is the relationships that we have.

Your smarts will come in handy because you will travel in a land of marvels. We humans -- plodding as we are -- will astonish ourselves. We'll invent ways to generate clean energy and a lot of it. Atom by atom， we'll assemble tiny machines that will enter cell walls and make repairs. This month comes the extraordinary but also inevitable news that we've synthesized life. In the coming years， we'll not only synthesize it， but we'll engineer it to specifications. I believe you'll even see us understand the human brain. Jules Verne， Mark Twain， Galileo， Newton -- all the curious from the ages would have wanted to be alive most of all right now. As a civilization， we will have so many gifts， just as you as individuals have so many individual gifts as you sit before me.

Never spend your money before you have it.

The function of leadership is to produce more leaders, not more followers.

The world owes all its onward impulses to men ill at ease; the happy man inevitably confines himself within ancient limits.
