In days of old a wandering youth happened upon a group of men working in a quarry. Stopping by the first man he said: "What are you doing?" The worker grimaced and groaned as he replied, "I am trying to shape this stone, and it is backbreaking work." Moving to the next man, the youth repeated the question. This man showed little emotion as he answered, "I am shaping a stone for a building." Moving to the third man, our traveler heard him singing as he worked. "What are you doing?" asked the youth. "I am helping to build a cathedral," the man proudly replied.
