A gentleman is magnanimous, but a villain has long-term relationships.

Confucius’ famous saying. A gentleman is well versed in affairs, so his dealings with others are like walking on a flat road, feeling safe and comfortable. A small person's mind is often obsessed with things, worrying about gains and losses, so he often has a feeling of sadness. A gentleman has a lifetime of happiness and no worries for a day. A villain has a lifetime of worries but no happiness for a day. This has the same meaning.

A gentleman seeks everything from himself, while a villain seeks everything from others

Confucius’ famous saying. The four views in "The Analects of Confucius" have the same purpose but slightly different texts. "Xueer" records: "Confucius said: 'If you don't worry about others, you don't know yourself; when you worry, you don't know others.'" It means that you don't have to worry about others not knowing me. What you should worry about is that I don't know others.

Learning without thinking will lead to failure; thinking without learning will lead to peril.

Confucius’ famous saying. "Wang" means confused. "Peril" has two meanings: one is critical, which means uncertainty. One is fatigue, mental fatigue and no gain. When solved in the past. This sentence can be combined with the chapter "Reviewing the past and learning the new". Confucius first advocated paying equal attention to learning and thinking, which had a profound influence on Confucian disciples. For example, Zixia talks about learning and thinking carefully and "The Doctrine of the Mean" talks about learning and thinking carefully, both of which believe that learning and thinking cannot be neglected.

Be sensitive to things but cautious in speaking.

Confucius’ famous saying. The words come from "The Analects of Confucius·Xueer": "Confucius said: 'A gentleman has nothing to eat to satisfy himself, and a place to live without seeking peace of mind. He is quick to do things but cautious in speaking.'" Also in "The Analects of Confucius·Li Ren": "A gentleman wants to be slow in speaking but is sensitive to words." Yu Xing". The meaning is the same. It means to be diligent and quick in doing things, but cautious in speaking.
