During childhood, they played games with fierce intensity, giving themselves as sacrifice to the game, for play was the chief business of growth, finding and making themselves in the world. Now when they are too old merely to play, to what shall they give themselves with fierce intensity? They cannot play for recreation, since they have not been used up. … Since each activity is not interesting to begin with, its value does not deepen and it does not bear much repetition. … In these circumstances, the inevitable tendency is to raise the ante of the compulsive useless activity.
Paul Goodman
