" The tension of the soul in unhappiness, which cultivates its strength; its horror at the sight of the great destruction; its inventiveness and bravery in bearing, enduring, interpreting, exploiting unhappiness, and whatever in the way of depth, mystery, mask, spirit, cleverness, greatness the heart has been granted - has it not been granted them through suffering, through the discipline of great suffering? "

― Friedrich Nietzsche , Beyond Good and Evil
