Chapter 1, Part 4 - Confucius

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 practiced the instructions of my teacher."
