It is said that there was an emperor in ancient Rome who often sent people to observe those condemned prisoners who were going to be sent to the arena to fight with wild animals the next day, and to see their performance the night before they died. If it is found that among the prisoners who are worried and sad, there is someone who can sleep soundly and keep his face unchanged, he will be released secretly the next morning and trained to be a soldier.

It is said that there was an emperor in China. When he met new courtiers, he always deliberately told them to wait outside, ignored them for a long time, and then secretly observed the performance of these people, sitting up and taking notice of those carefree and impatient courtiers.

Even those experts in bird breeding should deliberately scare those birds when choosing birds, and never bring the kind of birds that flap their wings when they are a little scared.

The strong in the previous three examples are likely to be born with strong stability or endurance. But from another angle, if a person is trained by perseverance from an early age and a bird stays in the crowd from an early age, is it possible to perform better?

The father of American President John F. Kennedy, in order to let his son see this scene, once let John F. Kennedy fly to Paris to attend a social gathering. Because he not only requires children to be polite and know how to greet people, but also hopes that John F. Kennedy has style and style! Everyone said, "Old Kennedy raised his children to be presidents when he was young."

Many Japanese companies send employees to temples to be tested by the precepts every winter. During the training, students should endure the cold without heaters and are not allowed to lie down and sleep at night. If they are not careful during meditation, they will be slapped on their backs with a ring board, and they are not allowed to shout pain. Because of this, they can endure what others can't stand and focus on what others can't, so they have outstanding performance in the international business arena. So, isn't the training the day after tomorrow very useful?

Having said these stories, I finally want to say:

A person's mind, tolerance and demeanor can often be expressed through small gestures. As for whether this kind of performance is ordinary demeanor or a fool's errand, it depends on your own practice.

See mystery for details, character for details, and spirit for details. Be a man, pay attention to details and be cautious about small things. The so-called trickle into a river and sand into a mountain peak all emphasize the importance of subtleties, and emphasize that only by focusing on and starting from subtleties can we realize our grand aspirations and achieve great undertakings.
