The word "promising future" is often used to praise a person, praising him for doing well now and saying that he will have greater development prospects in the future, which should not be underestimated. It can be expected and encountered, and it is also applicable to the future. Of course, this is more of a kind of wisdom, because the future is inherently unknown. Through understanding of oneself and through one's own efforts, unexpected and unforeseen situations can be reversed.
