2.? First, it reflects his style of doing things. When he has determined what he wants to do, he must stick to it and carry it out with strong execution. It shows that he has strong self-management ability and willpower.
3.? Generally, stars say that they exercise, either by taking photos to show their figure or by saying how hard they exercise. Few people will talk about the professional coach behind them. The fact is that there are professional fitness coaches behind the vest line of the stars. But few stars will say how powerful my fitness instructor is. Helping me build a good figure will only emphasize my own efforts. This kind of behavior is called self-beautification in social psychology, which is also human nature. LAY didn't emphasize how hard he worked to keep fit. He just said that fitness needs professional guidance, which can break through self-beautification and is higher than most people, especially when entertainment stars have more personality. This reflects from the side that he can look at himself and things around him objectively. The entertainment circle is a vanity fair, and it is common to hold high and step low. Many people can't find the north if they are popular.
Good self-management and willpower, as well as an objective view of yourself and things around you, are the more important qualities to do things well. I wouldn't be surprised if LAY made extraordinary achievements in the future, or really became the second full uncle.
