“It is not a lack of love, but a lack of friendship that makes unhappy marriages.”

That which does not kill us makes us stronger.

Without music, life would be a mistake.

What is done out of love always takes place beyond good and evil.

You must have chaos within you to give birth to a dancing star.

He who has a why to live can bear almost any how.

The higher we soar, the smaller we appear to those who cannot fly.

He who fights with monsters should look to it that he himself does not become a monster.
