Begin therefore with little things. Is a little oil spilled or a little wine stolen? Say to yourself, “This is the price paid for peace and tranquillity; and nothing is to be had for nothing.” And when you call your servant, consider that it is possible he may not come at your call; or, if he does, that he may not do what you wish. But it is not at all desirable for him, and very undesirable for you, that it should be in his power to cause you any disturbance.
