You exist only in what you do.

Most people have the will to win, few have the will to prepare to win.

Who has a harder fight than he who is striving to overcome himself.

Be true to your work, your word, and your friend.

Try to keep your soul young and quivering right up to old age.

A will finds a way.

My religion is very simple. My religion is kindness.

Fortune favors the prepared mind.

The true method of knowledge is experiment.

Surprise is the greatest gift which life can grant us.
