Throughout the ages, those who have accomplished great things have been good at making choices and not sticking to trivial matters. Things that exist in real life contain many kinds of contradictions, and it is impossible for people to take them into full consideration. Therefore, one can only be good at grasping the main contradictions and main aspects of contradictions in things. . Only by clarifying the important status of the master and not sticking to small details can we devote most of our energy to the process of resolving the main contradictions and main aspects of the contradiction. Only by reducing the obstacles of trivial matters can we achieve faster success. There is a saying in the Red Gate Banquet: A big act does not take care of the details, and a big gift does not hesitate to make small concessions. It means that you don’t need to worry about the minutiae when doing big things, and you don’t need to worry about small humility when giving a big gift. This is also how you should be as a human being. You should be good at making choices in order to achieve great things.
