Why be concerned about others, come to that, when you've outdone your own self? Set yourself a limit which you couldn't even exceed if you wanted to, and say good-bye at last to those deceptive prizes more precious to those who hope for them than to those who have won them. If there were anything substantial in them they would sooner or later bring a sense of fullness; as it is they simply aggravate the thirst of those who swallow them.
