A water bearer worked for a merchant who lived on top of a hill everyday he had to walk down the hill to collect water from a stream. He would place  it in two pots which he hung on each end of a pole and carried over his shoulders one of the pots was perfect and always delivered a full potation of water at the end of the long walk. The other pot had a crack and would always arrive half full. The perfect pot was proud of its accomplishments whilst the poor cracked pot was ashamed of his own imperfection.
