This is an old saying of China, and there is no last sentence. "People are expensive and self-aware" means that it is the wisest and most valuable to be able to know yourself clearly and treat yourself well.

It's important to know your limitations.

China has a classic saying: "You should know yourself". On the gate of a temple of wisdom in ancient Greece, there is also a proverb: "Know yourself", which the ancient Greeks regarded as an "Oracle" and a symbol of the highest wisdom. Many philosophers have warned people that visibility and insight are very important to life and even human beings.

Self-knowledge means knowing yourself and knowing yourself. Some people may say, "I am myself. How can I say that I don't know myself? " Actually, it is not. Some people can understand others, the environment, the society and even the world, but they just don't know much about themselves. It's hard to be self-aware. The world is a vast sea of people. Few people can really understand themselves, but many people can't. Otherwise, why are there exhortations like "people should know themselves" at all times and in all countries?

In real life, some people, who speak logically and have the ability to do things, are often at a loss. Some people, who aim high, can really give them room to display, but they are often disappointed and regretful. Some people are arrogant; Some people are complacent and do not make progress; Some people are carried away by profits. Most of them don't know their own depth and geometry, and they lack the self-knowledge that life should have. It is obviously self-deception, and it is also very high.
