Smart, professionally called excellent intelligence. Intelligence generally includes three aspects: first, the ability of perception and memory, especially observation, is the basic form of intelligence; The second is the ability of abstract generalization (including imagination), which is the core part of intelligence; The third is creativity, which is the highest expression of intelligence. Intelligence enables people to learn knowledge, understand things, adapt to the environment, solve problems and create inventions. Stupidity, that is, mental retardation, is theoretically the antonym of intelligence. These are all professional questions.

A wise man knows that he is smart and that others are smarter than himself. Every smart person can always find someone smarter than himself and regard them as his goal or an example to learn from. At the same time, they will know more about their stupidity and shortcomings than the average person. Because they know themselves, are good at reflecting on their own stupidity and shortcomings, and dare to change their shortcomings and mistakes and some stupid practices in reflection. In short, smart people will listen to other people's opinions and constantly reflect on themselves.

Stupid people usually only know their own cleverness, don't know their own stupidity, and don't admit their own shortcomings and mistakes. Every stupid person can always find at least one person who is more stupid than himself, or at least someone who is more stupid than himself in some way to raise himself and try his best to make himself taller. Because they feel that they are always right and there is no need to correct their shortcomings and mistakes, they always add mistakes and get farther and farther away from their goals.

There is a difference between cleverness and stupidity. A wise man who is open-minded and generous and doesn't care about the gains and losses of personal grievances belongs to a fool and a wise man. Such people are the pillars of the country; Cleverness with calculation, duplicity and flattery belongs to cleverness and stupidity. They are usually moths.

If you think someone is smart and praise him, but he blushes quietly, or generally ranks third, this person may be really smart. Of course, cleverness is not what others say, but that he is really excellent and made it by himself.

However, if you meet someone for the first time and they say you are stupid, be careful. He may have ulterior motives. Because a truly stupid person will never say that he is stupid.
