There once lived a powerful king who undertook an expedition to conquer foreign lands. His wise counselor asked him, "Great king, to what purpose do you set out on this endeavor?""To become master of Asia," the king replied."And then what?" asked the counselor."I shall invade Arabia," said the king."And after that?""I shall conquer Europe and Africa; and finally, when the whole world is under me, I shall rest and live at ease."To this the wise counselor retorted, "But what keeps you from resting and living at ease here and now, if that is all you want? You could settle down this very day without the trouble and risks."
