Discipline Is Destiny: The Power of Self-Control (The Stoic Virtues Series)

by Ryan Holiday

His greatness, like all true greatness, was not rooted in aggression or ego or his appetites or a vast fortune, but in simplicity and restraint—in how he commanded himself, which in turn made him worthy of commanding others. Contrast him with the conquerors of his time: Hitler. Mussolini. Stalin. Contrast him even with his contemporaries: MacArthur. Patton. Montgomery. Contrast him with his peers of the past: Alexander the Great. Xerxes. Napoleon. In the end, what endures, what we truly marvel at, is not the ambition but the self-mastery. The self-awareness. The temperance. As a young man, Eisenhower’s mother had quoted him a verse from the Book of Proverbs, “He that is slow to anger is better than the mighty,” she had told him, “and he that ruleth his spirit than he that taketh a city.” She taught him the same lesson that Seneca himself tried to instill in the rulers he advised, that “Most powerful is he who has himself in his own power.”
