I'm sorry I wrote you such a long letter; I didn't have time to write a short one.

If we go down into ourselves, we find that we possess exactly what we desire.

The greatest sin is to think yourself weak

The more you lose yourself in something bigger than yourself, the more energy you will have.

The starting point of all achievement is desire.

I trust that everything happens for a reason, even if we are not wise enough to see it.

We were a family who had come from nothing and now we had respect from French people of all sorts.

Others have seen what is and asked why. I have seen what could be and asked why not.

Alone we can do so little; together we can do so much.

We should not give up and we should not allow the problem to defeat us.

The time is always right to do the right thing

Imagination will often carry us to worlds that never were, but without it we go nowhere.

If you're not prepared to be wrong, you'll never come up with anything original.

Know thyself.

Climbing to the top demands strength, whether it is to the top of Mount Everest or to the top of your career.

The crisis of today is the joke of tomorrow.

I can be changed by what happens to me. But I refuse to be reduced by it.

A man can't soar too high, when he flies with his own wings.

Memories of our lives, of our works and our deeds will continue in others.

Everything I've ever done was out of fear of being mediocre.

It's kind of fun to do the impossible.
