As soon as you trust yourself, you will know how to live.

The power to do good is also the power to do harm.

What sunshine is to flowers, smiles are to humanity.

We areall faced with a series of great opportunities brilliantly disguised asimpossible situations.

Voilence is a Just when kindness is vain

To beprepared is half the victory.

No man is the whole himself; his friends are the rest of him.

Men are mortal, but ideas are immortal.
