"God grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom always to tell the difference"

     

        The prayer on the wall shows that Billy has hope to keep going. The book also tells us that the framed prayer has also given his patients the hope to keep going on. Believing in something better than what your situation is at the time is enough to help someone take the next step. Someone believing in you gives you this security that nothing else can give you and I truly believe that is what the prayer gave Billy and others who encountered it.
