“The most spiritual men, as the strongest, find their happiness where others would find their destruction: in the labyrinth, in hardness against themselves and others, in experiments.
Their joy is self-conquest.
Difficult tasks are a privilege to them, to play with burdens that crush others, a recreation. They are the most venerable kind of man: that does not preclude their being the most cheerful and the kindliest.”
— Friedrich Nietzsche
