Voters quickly forget what a man says.

A public man must never forget that he loses his usefulness when he as an individual, rather than his policy, becomes the issue.

A man who has never lost himself in a cause bigger than himself has missed one of life's mountaintop experiences. Only in losing himself does he find himself. Only then does he discover all the latent strengths he never knew he had and which otherwise would have remained dormant.

We must never forget that if the war in Vietnam is lost ... the right of free speech will be extinguished throughout the world.

Defeat doesn't finish a man - quit does. A man is not finished when he's defeated. He's finished when he quits.

For one priceless moment in the whole history of man, all of the people on this earth are truly one. One in their pride at what you have done, one in our prayers that you will return safely to earth.
