Keep your mouth shut, and close up the doors of sight and sound, and as long as you live you will have no vexation. But open your mouth, or become inquisitive, and you will be in trouble all your life long.
LaoziOf all that is good, sublimity is supreme. Succeeding is the coming together of all that is beautiful. Furtherance is the agreement of all that is just. Perseverance is the foundation of all actions.
Laozi
