That which does not kill us makes us stronger. - Friedrich Nietzsche

"Admiration for a quality or an art can be so strong that it deters us from striving to possess it."

"No one can construct for you the bridge upon which precisely you must cross the stream of life, no one but you yourself alone."

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

"Ultimately, it is the desire, not the desired, that we love."

"The life of the enemy . Whoever lives for the sake of combating an enemy has an interest in the enemy's staying alive."
