There is an allusion that a big American investor tried to communicate with his subordinates only through handwritten notes (note that it is handwritten, not email) and found that the work efficiency was greatly improved. The reason is that handwritten words are often concise, without adjectives and emotional expressions, so the meaning is clear and the main points are prominent.

Talking too much is easy to miss the main points and the key points are vague. Of course, it is better to be concise and clear, saving two aspects of time.

"Only it is" and "yes" mean "objective", "true" and "meaningful" respectively. It's no use talking too much, and it will be counterproductive. In a short time, if you want to know people, you should not only listen to their manners, appearances and manners, but also listen to what they say. If this person is not allowed to speak, talks too much nonsense, complains too much, accuses others too much, exaggerates too much and flatters too much, then these all reflect some characteristics of this person's thinking mode, so that we can understand a person.
