The life of our class, of the wealthy and the learned, was not only repulsive to me but had lost all meaning. The sum of our action and thinking, of our science and art, all of it struck me as the overindulgences of a spoiled child.
Leo TolstoyA good player who loses at chess is genuinely convinced hat he has lost because of a mistake, and he looks for this mistake in the beginning of his game, but forgets that there were also mistakes at ever step in the course of the game, that none of his moves was perfect. The mistake he pays attention to is conspicuous only because his opponent took advantage of it.
