If a man has talent and can't use it, he's failed. If he uses only half of it, he has partly failed. If he uses the whole of it, he has succeeded, and won a satisfaction and triumph few men ever know.

You can't go home again

If a man has a talent and cannot use it, he has failed. If he has a talent and uses only half of it, he has partly failed. If he has a talent and learns somehow to use the whole of it, he has gloriously succeeded . . .

A man who fails well is greater than one who succeeds badly.

Success is what you do with your ability. It's how you use your talent.

What is it that makes a man willing to sit up on top of an enormous Roman candle, such as a Redstone, Atlas, Titan or Saturn rocket, and wait for someone to light the fuse?
