Part of a tiny story I like:

Three men, all engaged at the same employment, were asked what they were doing. One said he was making five dollars a day. Another replied that he was cutting stone. The third said he was building a cathedral. The difference was not in what they were actually doing, although the spirit of the third might quite possibly have made him the more expert at his task. They were all earning the same wage: they were all cutting stone; but only one held in his mind that he was helping build a great edifice. Life meant more to him than to his mates, because he saw further and more clearly.
