Letter 18 — On Festivals and Fasting (§6)

“It is precisely in times of immunity from care that the soul should toughen itself beforehand for occasions of greater stress, and it is while Fortune is kind that it should fortify itself against her violence. In days of peace the soldier performs manœuvres, throws up earthworks with no enemy in sight, and wearies himself by gratuitous toil, in order that he may be equal to unavoidable toil. If you would not have a man flinch when the crisis comes, train him before it comes. Such is the course which those men have followed who, in their imitation of poverty, have every month come almost to want, that they might never recoil from what they had so often rehearsed.”
