“Mark Twain once told a story about a man who scoured the planet looking for the greatest general who ever lived. When the man was informed that the person he sought had already died and gone to heaven, he made a trip to the Pearly Gates to look for him. Saint Peter pointed at a regular-looking Joe. “That isn’t the greatest of all generals,” protested the man. “I knew that person when he lived on Earth, and he was only a cobbler.” “I know that,” said Saint Peter, “but if he had been a general, he would have been the greatest of them all.”
