In days of peace the soldier performs maneuvers, throws up earthworks with no enemy in sight, and is wearied by unnecessary toil, in order that he may be equal to that which is necessary. If you would not have a man flinch when the crisis comes, train him before it comes. Such is the course those men have followed who, in their imitation of poverty, have every month left themselves almost destitute, that they might never recoil from what they had often rehearsed. Seneca, Epistles 18.6
