You have enemies? Good. That means you've stood up for something, sometime in your life.

Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's relativity.

Speak only if it improves upon the silence.

Bessie Braddock: Sir, you are drunk.
Churchill: And you, madam, are ugly. But in the morning, I shall be sober.

Life is like riding a bicycle. To keep your balance you must keep moving.

Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

Try to become not a man of success, but try rather to become a man of value.

Coincidence is God's way of remaining anonymous.

I'm not an atheist and I don't think I can call myself a pantheist. We are in the position of a little child entering a huge library filled with books in many different languages.

I do not know with what weapons World War III will be fought, but World War IV will be fought with sticks and stones. Letter to Harry S. Truman.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

To believe in something, and not live it, is dishonest.

Everything has its beauty but not everyone sees it.

I want to stay as close to the edge as I can without going over. Out on the edge you see all kinds of things you can't see from the center.

The search for truth is more precious than its possession.
