曾子曰:“吾日三省吾身:为人谋而不忠乎?与朋友交而不信乎?传不习乎?”
Master Zeng said, “Daily I examine my person on three counts. In my undertakings on behalf of other people, have I failed to do my utmost ( zhong 忠 )? In my interactions with colleagues and friends, have I failed to make good on my word ( xin 信 )? In what has been passed on to me, have I failed to carry it into practice?”
