All that really belongs to us is time; even he who has nothing else has that.

Life is a path that you beat while you walk it.

We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the universe. That makes us something very special.

A luxury, once enjoyed, becomes a necessity.

Mistakes are good, but improved mistakes is success.

Hope arouses, as nothing else can arouse, a passion for the possible.
