First of all, psychological research results tell us that people's energy is limited. Therefore, if you want to achieve great things, you must concentrate on this field, as the saying goes. If you confine yourself to trivial matters and spend too much energy and time on unprincipled trivial matters, it will inevitably hinder the achievement of great things. Therefore, from the perspective of what should be, those who achieve great things are informal.
Secondly, looking at people who have achieved great things through the ages, we can find their common characteristics: long-term vision and keen insight and foresight on the development of things. This enables them to recognize the position and function of the section, not to focus too much on these trivial matters that have nothing to do with principles, but also to focus on the overall situation and get rid of the section in front of them. Therefore, judging from the specific theme of the debate, those who achieve great things are informal.
Thirdly, detaining a small section has a negative impact on achieving great things. It limits people's vision, consumes people's time and energy, and wastes really important undertakings. How can people achieve great things if they concentrate on trivial things all day and persevere? Therefore, it is difficult for detained people to achieve great things, and those who achieve great things are informal. while
However, I don't think people who achieve great things are idiots who only do research and don't listen to human affairs. They should also take care of their own lives. However, taking care of his life while doing his own thing does not mean that he is limited to details, because he does not stick to details and spends too much time and energy on these things and cannot extricate himself from the details. It is a general and abstract overall concept. Any small matter is only a concrete manifestation of a certain aspect of the festival, and can not be used to replace the concept of the festival. This is also a universal premise. To sum up, from the perspective of theory and facts, from the perspective of the special subject of great things, and from the perspective of the relationship between restraint and great things, it is proved that great things are unrestricted.
