Keep this thought handy when you fee a fit of rage coming on- it isn't manly to be enraged. Rather, gentleness and civility are more human, and therefore manlier. A real man doesn't give way to anger and discontent, and such a person has strength, courage and endurance- unlike the angry and complaining. The nearer a man comes to a calm mind, the close he is to strength.

—Marcus Aurelius, Meditations, 11.18.5b
