The 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 NietzscheI too have been in the underworld, as was Odysseus, and I will often be there again; not only sheep have I sacrificed so as to beable to speak with a few dead souls, but neither have I spared my own blood as well.
Friedrich Nietzsche
