“Perhaps you have heard the story of Christopher Wren, one of the greatest of English architects, who walked one day unrecognized among the men who were at work upon the building of St. Paul’s cathedral in London which he had designed. ”What are you doing?” he inquired of one of the workmen, and the man replied, “I am cutting a piece of stone.” As he went on he put the same question to another man, and the man replied, “I am earning five shillings twopence a day.” And to a third man he addressed the same inquiry and the man answered, “I am helping Sir Christopher Wren build a beautiful cathedral.” That man had vision. He could see beyond the cutting of the stone, beyond the earning of his daily wage, to the creation of a work of art—the building of a great cathedral. And in your life it is important for you to strive to attain a vision of the larger whole.” – (Louise Bush-Brown, http://www.bartleby.com/73/458.html)
