I daily examine myself on three points: In planning for others, have I failed in conscientiousness? In intercourse with friends, have I been insincere? And have I failed to practice what I have been taught?
When a person should be spoken with, and you don't speak with them, you lose them. When a person shouldn't be spoken with and you speak to them, you waste your breath. The wise do not lose people, nor do they waste their breath.
When the Superior Man eats he does not try to stuff himself; at rest he does not seek perfect comfort; he is diligent in his work and careful in speech. He avails himself to people of the Tao and thereby corrects himself. This is the kind of person of whom you can say, "he loves learning."
