“To elude boredom man either works harder than is required to satisfy his other needs or he invents play, that is to say work designed to assuage no other need than the need for work as such. He who has become tired of play, and who has no fresh needs that require him to work, is sometimes overtaken by a longing for a third condition which stands in the same relation to play as floating does to dancing and dancing to walking — for a state of serene agitation: it is the artist’s and philosopher’s vision of happiness.”

– Friedrich Nietzsche, Human, All Too Human, 611
