Confucius Each day I examine myself in three ways

『1-4』曾子曰：「吾日三省吾身、爲人謀而不忠乎。與朋友交而不信乎。傳不習乎。 」

　　[1:4] Tseng Tzu said: "Each day I examine myself in three ways: in doing things for others, have I been disloyal? In my interactions with friends, have I been untrustworthy? Have not practiced what I have preached?"
