A noble person is humble. A sedate and modest person always keeps a low profile, and is aware of his own weaknesses. A person who keeps a low profile may be able to reach high goals. A person who is aware of his own weaknesses may be able to accomplish high morality. (Wenzi)

Thinking that I am getting on in age, without much talent, and only have a shallow understanding of some concepts expounded in The Book of Changes, I must hurry to cultivate myself, keep a low profile, and make up my own weaknesses.  (Zheng Guanying: Preface to Warning Words in a Prosperous Society)
