Being the fool is not the same as acting the fool: you can't decide to be playful, or foolish, for an hour a day, as if it were yet another task to add to your campaign of self-improvement. It's rather the result of a relaxation of the rules and goals that you normally run your life by. A softening of the beliefs that hold up your world and your idea of who you think you are. The pleasure of foolishness lies in large part in the absence of self-consciousness; in the self-forgetting that comes in a moment of abandon.
