Human personality can be roughly divided into introvert and extrovert.
They have their own advantages and disadvantages.
Introverts are generally not good at words and social, slow movements, but like to think, calm in the face of things, once they grasp a certain law, they will use it beyond the ordinary, so they are good at winning the strong with the weak and attacking later.
Extroverted people are optimistic and cheerful, good at speech and socialization, strong in action learning ability, good at winning the weak with the strong, preemptive, but easy to be impulsive, not well thought out about things, and often experience failure.
Psychologists believe that personality can generally be changed.
That is, introverts can become very extroverted; conversely, extroverts can also learn some of the advantages of introversion.
For example, Li Ka-shing is introverted, but he strives to restrain this introversion, and eventually sells people with high skills and extroverts.

Li
The general acquired extroversion has more advantages than the natural extroversion.
For example, Ma Yun, probably no one said that he was introverted, in fact, he was born introverted, otherwise he would not have so many thoughts.
Ma
He restrained his natural introversion and eventually achieved a personality that was more extroverted than an extrovert.
Extroverts, on the other hand, may also become cautious and calm, and may also form some thoughts.
For example, Li Shimin, who has hardly lost a war, and he also wrote a book about his governing experience for his son to read (and later emperors also enshrined it as a bible), which is quite difficult for an extroverted person.
Li Shimin
Another example is Washington, as an extrovert, did not think things through carefully enough, resulting in his almost repeated defeats in the war at the beginning, but later, he gradually restrained his outgoing shortcomings, became cautious, and finally won again and again.

Introverts tend to look ahead and strive for perfection.
For example, Liu Bei and Zhuge Liang, they can be called perfect people.

But because they are too much in pursuit of perfection, they lose opportunities again and again.
For example, in order to pursue perfection and express his righteousness toward Guan Yu, Liu Bei disregarded Zhuge Liang's plan to unite Wu and resist Cao, and sent troops to fight Wu, and finally suffered a great defeat.
Zhuge Liang (stills)
In order to pursue perfection, Zhuge Liang led to the failure of the Six Qishan Dynasty Wei Gong.
Extroverts, while not so perfect, can seize opportunities again and again.
For example, Cao Cao and Chen Gong fled to Lü Bohao's house, and Lü Bohao's family killed pigs to entertain them, and they mistakenly thought that they were going to kill them, so they killed all the people who killed the pigs.
Statue of Cao Cao
The introverted Chen Gong is very remorseful, while the extroverted Cao Cao can't manage so much.
Not only did he not blame himself, but he feared that Lü Bohao would retaliate and killed Lü Bohao.
Introverts generally can't do such a terrible thing.
Of course, there are also some extroverts who learn from introverts who pursue perfection.
For example, Li Shimin, when he decided to kill Li Jiancheng and Li Yuanji, he also talked about brotherhood and wanted to make himself a perfect person.
However, after all, he was not an introvert and could not be as perfect as Liu Bei and Zhuge Liang.
For example, he heard Yuan Tiangang say that in the future, a woman surnamed Wu would usurp the Tang Dynasty, and then heard that his general Li Junxian was called "Five Ladies", so he killed him indiscriminately.
Introverts often care about their own reputation, and although Li Shimin also cares about his reputation, he ultimately cannot control himself in the face of greater interests.
The Chinese government, led by the Chinese Communist Party, is generally considered introverted because the Chinese government cares a lot about its reputation.
The U.S. government, on the other hand, is an extroverted representative who tends to care more about practical interests.
But it cannot be said that Chinese does not care about actual interests at all, but often reputation precedes actual interests.
Introverts tend to humbly claim to be weak, while extroverts are more likely to flaunt themselves and label themselves as strong.
But people who don't know the truth tend to follow extroverts.
Because our country is very introverted and rarely flaunts its achievements, many countries are still willing to be friends with the arrogant United States.
So, is it an introverted personality, or an extroverted personality?
Generally speaking, it is the extroversion of the personality that restrains the outgoing shortcomings, and the introversion that restrains the introvert shortcomings of the personality is the best.
That is, the combination of introversion and extroversion is the best.
For example, Li Shimin, who restrained the shortcomings of extrovertedness and did not care about reputation, did things again and again, and finally became an almost perfect character;
Another example is Zhuge Liang, who restrained the shortcomings of introverted personality who only loved fame and did not fight for practical interests, and became not only the embodiment of loyalty, but also the embodiment of wisdom.
On the other hand, Wu Zetian, in order to obtain the throne, used all kinds of means to spare her reputation, although she also had praiseworthy places, but her status was far from the same as that of Emperor Taizong.

On the other hand, Liu Bei, although he loved his reputation, he was indecisive about the interests in hand, and eventually lost the great country in vain.
So, if you are introverted, then try to restrain the shortcomings of your introverted personality.
For example, if you don't like to deal with people, you have to communicate with people more, don't be shy, and eventually you will become a social master who is more social than those who are extroverted;
If you often lose your interests for the sake of fame, you must also learn to say no.
At the same time, you also need to play to the advantages of your introverted personality, such as successfully mastering a skill, you can compete for the first place.
Another example is that you cherish your reputation and have won you a lot of good reputation.
If you are extroverted, then you have to try to restrain your own extroverted shortcomings;
For example, to do things impulsively, to do everything to think twice before acting;
Another example is to be in a hurry to do things, to learn to take the zigzag path, and to win fame for yourself while getting benefits.
At the same time, give play to the advantages of outgoing personality.
For example, be good at dealing with people, be good at obtaining benefits, but pay attention to your own reputation when obtaining benefits.
May every introvert and extrovert in the world overcome the weaknesses of their own personality and achieve a better self.
