“Keep this thought handy when you feel 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 closer he is to strength.”

Marcus Aurelius, Meditations, via The Daily Stoic (Page 41)
