It is not a lack of love, but a lack of friendship that make... - Friedrich Nietzsche

"I assess the power of a will by how much resistance, pain, torture it endures and knows how to turn to its advantage"

"The man of knowledge must be able not only to love his enemies but also to hate his friends."

"Not necessity, not desire - no, the love of power is the demon of men. Let them have everything - health, food, a place to live, entertainment - they are and remain unhappy and low-spirited: for the demon waits and waits and will be satisfied."

"The overman...Who has organized the chaos of his passions, given style to his character, and become creative. Aware of life's terrors, he affirms life without resentment."

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