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 man's knowledge is sufficient to attain, and his virtue is not sufficient to enable him to hold, whatever he may have gained, he will lose again.
Sincerity becomes apparent. From being apparent, it becomes manifest. From being manifest, it becomes brilliant. Brilliant, it affects others. Affecting others, they are changed by it. Changed by it, they are transformed. It is only he who is possessed of the most complete sincerity that can exist under heaven, who can transform.
