text: This is sound practice, – to refrain from associating with men of different stamp and different aims. And I am indeed confident that you cannot be warped, that you will stick to your purpose, even though the crowd may surround and seek to distract you. What, then, is on my mind? I am not afraid lest they work a change in you; but I am afraid lest they may hinder your progress. And much harm is done even by one who holds you back, especially since life is so short; and we make it still shorter by our unsteadiness, by making ever fresh beginnings at life, now one and immediately another. We break up life into little bits, and fritter it away. Hasten ahead, then, dearest Lucilius, and reflect how greatly you would quicken your speed if an enemy were at your back, or if you suspected the cavalry were approaching and pressing hard upon your steps as you fled. It is true; the enemy is indeed pressing upon you; you should therefore increase your speed and escape away and reach a safe position, remembering continually what a noble thing it is to round out your life before death comes, and then await in peace the remaining portion of your time, claiming nothing for yourself, since you are in possession of the happy life; for such a life is not made happier for being longer. O when shall you see the time when you shall know that time means nothing to you, when you shall be peaceful and calm, careless of the morrow, because you are enjoying your life to the full?
