Negative Visualization: Foreseeing Bad Stuff “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 maneuvers, throws up earthworks with no enemy in sight, and wearies himself by unnecessary toil, in order that he may be equal when it is necessary. If you would not have a man flinch when the crisis comes, train him before it comes.” – Seneca
