Be able to keep a secret or promise when you know in your heart that it is the right thing to do.

A good idea will keep you awake during the morning, but a great idea will keep you awake during the night.

Suppose you're on a game show, and you're given the choice of three doors. Behind one door is a car, the others, goats. You pick a door, say #1, and the host, who knows what's behind the doors, opens another door, say #3, which has a goat. He says to you: 'Do you want to pick door #2?' Is it to your advantage to switch your choice of doors?

I believe Picasso's success is just one small part of the broader modern phenomenon of artists themselves rejecting serious art- perhaps partly because serious art takes so much time and energy and talent to produce-in favor of what I call `impulse art': art work that is quick and easy, at least by comparison.

The chess player who develops the ability to play two dozen boards at a time will benefit from learning to compress his or her analysis into less time.

I believe that one becomes stronger emotionally by taking life less personally. If your employer criticizes your report, don't take it personally. Instead, find out what's needed and fix it. If your girlfriend laughs at your tie, don't take it personally. Find another tie or find another girlfriend.

Multi-tasking arises out of distraction itself.
