Put from you the belief that 'I have been wronged', and with it will go the feeling. Reject your sense of injury, and the injury itself disappears.
Marcus AureliusIf any man can convince me and bring home to me that I do not think or act aright, gladly will I change; for I search after truth, by which man never yet was harmed. But he is harmed who abideth on still in his deception and ignorance.
Marcus AureliusCultivate these, then, for they are wholly within your power: sincerity and dignity; industriousness; and sobriety. Avoid grumbling, be frugal, considerate, and frank; be temperate in manner and speech; carry yourself with authority.
Marcus Aurelius
