You see things; you say, 'Why?' But I dream things that never were; and I say 'Why not?

When every physical and mental resource is focused, one's power to solve a problem multiplies tremendously.

If you can't feed a hundred people, then just feed one.

If you can dream it, you can do it.

However many holy words you read, however many you speak, what good will they do you if you do not act on upon them?

My optimism wears heavy boots and is loud.

You must never be fearful about what you are doing when it is right.

If my life is going to mean anything, I have to live it myself.

I invented my life by taking for granted that everything I did not like would have an opposite, which I would like.

Only those are fit to live who do not fear to die; and none are fit to die who have shrunk from the joy of life and the duty of life. Both life and death are parts of the same Great Adventure.

A pure hand needs no glove to cover it.

Knowing what's right doesn't mean much unless you do what's right.

With realization of one's own potential and self-confidence in one's ability, one can build a better world.

March on. Do not tarry. To go forward is to move toward perfection. March on, and fear not the thorns, or the sharp stones on life's path.

I have always found that mercy bears richer fruits than strict justice.

People die from typewriters falling on their heads.

People who say it cannot be done should not interrupt those who are doing it.

People are capable, at any time in their lives, of doing what they dream of.

You'll never get ahead of anyone as long as you try to get even with him.

Never tell all you know-not even to the person you know best.
