According to an ancient story, one evening, John was playing with an animal. A young man holding a bow commented on the disciple’s “waste” of time. John asked the man to string his bow and shoot an arrow. He did so, and then unstrung his bow. John asked why he unstrung it. The young man replied that his bow would become weak and useless if it were kept always tightly strung. John replied that times of fun and relaxation do the same thing for the human spirit— they keep us at our best.
