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。
Modern Chinese Guide
曾子说：我每天多次反省自己：替别人办事有没有不尽心？和朋友交往有没有不诚信？老师传授的道理有没有认真温习实践？
James Legge Translation
The philosopher Tsang said, "I daily examine myself on three points:—whether, in transacting business for others, I may have been not faithful;—whether, in intercourse with friends, I may have been not sincere;—whether I may have not mastered and practised the instructions of my teacher."
