Whatever you do, do it with all your heart and soul.

Always do one thing less than you think you can do.

Only as you do know yourself can your brain serve you as a sharp and efficient tool. Know your own failings, passions, and prejudices so you can separate them from what you see.

Chance sometimes opens the door, but luck belongs to the good players.

Even when we know what is right, too often we fail to act. More often we grab greedily for the day, letting tomorrow bring what it will, putting off the unpleasant and unpopular.

Most of the successful people I know mostly listen, not talk.

Never pay the slightest attention to what a company president ever says about his stock.
