Sometimes even to live is an act of courage.

The bravest sight in the world is to see a great man struggling against adversity.

It is not because things are difficult that we do not dare; it is because we do not dare that things are difficult.

A gem cannot be polished without friction, nor a man perfected without trials.

Nothing happens to the wise man against his expectation.

No man is more unhappy than he who never faces adversity. For he is not permitted to prove himself.

Life, if well lived, is long enough.

Fire tests gold, suffering tests brave men.

True happiness is to enjoy the present, without anxious dependence upon the future.

The good never dies.
