"The opposite of play is not work--the opposite of play is depression." He explains, "Respecting our biologically programmed need for play can transform work. It can bring back excitement and newness to our job. Play helps us deal with difficulties, provides a sense of expansiveness, promotes mastery of our craft, and is an essential part of the creative process. Most important, true play that comes from our own inner needs and desires is the only path to finding lasting joy and satisfaction in our work. In the long run, work does not work without play."2"
