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.
ConfuciusThe Master said, I set my heart on the Way, base myself on virtue, lean upon benevolence for support and take my recreation in the arts.
ConfuciusThe superior man, even when he is not moving, has a feeling of reverence, and while he speaks not, he has the feeling of truthfulness.
