If thou workest at that which is before thee ... expecting nothing, fearing nothing, but satisfied with thy present activity according to Nature, and with heroic truth in every word and sound which thou utterest, thou wilt live happy. And there is no man who is able to prevent this.
Marcus AureliusLive out your life in truth and justice, tolerant of those who are neither true nor just.
Marcus AureliusBe not unwilling in what thou doest, neither selfish nor unadvised nor obstinate; let not over-refinement deck out thy thought; be not wordy nor a busybody.
Marcus AureliusEvery moment think steadily as a Roman and a man to do what thou hast in hand with perfect and simple dignity, and feeling of affection, and freedom, and justice; and to give thyself relief from all other thoughts. And thou wilt give thyself relief, if thou doest every act of thy life as if it were the last, laying aside all carelessness and passionate aversion from the commands of reason, and all hypocrisy, and self-love, and discontent with the portion which has been given to thee.
Marcus Aurelius
