If you wish your children and your wife and your friends to live forever, you are foolish, for you wish things to be in your power which are not so, and what belongs to others to be your own. So likewise, if you wish your servant to be without fault, you are foolish, for you wish vice not to be vice but something else. But if you wish not to be disappointed in your desires, that is in your own power. Exercise, therefore, what is in your power. A man’s master is he who is able to confer or remove whatever that man seeks or shuns. Whoever then would be free, let him wish nothing, let him decline nothing, which depends on others; else he must necessarily be a slave. XV Remember that you must behave as at a banquet. Is anything brought round to you? Put out your hand and take a moderate share. Does it pass by you? Do not stop it. Is it not yet come? Do not yearn in desire toward it, but wait till it reaches you. So with regard to children, wife, office, riches; and you will some time or other be worthy to feast with the gods. And if you do not so much as take the things which are set before you, but are able even to forego them, then you will not only be worthy to feast with the gods, but to rule with them also. For, by thus doing, Diogenes and Heraclitus, and others like them, deservedly became divine, and were so recognized. XVI When you see anyone weeping for grief, either that his son has gone abroad or that he has suffered in his affairs, take care not to be overcome by the apparent evil, but discriminate and be ready to say, “What hurts this man is not this occurrence itself—for another man might not be hurt by it—but the view he chooses to take of it.” As far as conversation goes, however, do not disdain to accommodate yourself to him and, if need be, to groan with him. Take heed, however, not to groan inwardly, too. XVII Remember that you are an actor in a drama of such sort as the Author chooses—if short, then in a short one; if long, then in a long one. If it be his pleasure that you should enact a poor man, or a cripple, or a ruler, or a private citizen, see that you act it well. For this is your business—to act well the given part, but to choose it belongs to another. XVIII When a raven happens to croak unluckily, be not overcome by appearances, but discriminate and say, “Nothing is portended to _me_, either to my paltry body, or property, or reputation, or children, or wife. But to _me_ all portents are lucky if I will. For whatsoever happens, it belongs to me to derive advantage therefrom.” XIX
