He divines remedies against injuries; he knows how to turn serious accidents to his own advantage; whatever does not kill him makes him stronger
Friedrich NietzscheThe most intelligent men, like the strongest, find their happiness where others would find only disaster: in the labyrinth, in being hard with themselves and with others, in effort; their delight is self-mastery; in them asceticism becomes second nature, a necessity, as instinct.
Friedrich Nietzsche
