Focus is the secret of power-attention distribution

It seems like Napoleon said that focus is the secret of power. I think it is, but it seems that it is always impossible to do so, it is difficult to concentrate on one thing. Today, I am going to be more clear about this section. My attention is divided into several aspects. How can I get my attention.
There is a searchlight in our hearts. Every moment, we can only recognize where it shines. This is attention. It brings our hearts from one place to another. Under normal circumstances, our attention should be constantly switched between the three fields, which are sensory perception, action control and psychological feeling.
Perception provides us with information about the external world and physical conditions. When I saw a car on the road and heard someone calling you nearby, I felt chest tightness and muscle pain after running. Or if you don't eat for a long time, you are hungry. These are all sensory content.
You have to perform various actions every day. Are these actions correct? Decent? All you need to consider. This is a category of action control.
At the same time, you will also feel your inner world. You know what you are thinking, and you can feel your emotions and desires.
As long as we are moving, our attention will keep switching between the three.
A. You will think about problems while riding a bicycle, but at the intersection, You have to observe the passing vehicles. At this time, pay attention to switching from the inner world to perception.
B. When you are sitting under the stage, you will observe the surrounding conditions. If you speak on stage, your attention will be shifted to your own manners. In this case, attention is transferred from sensory perception to action control.
C. The student union is distracted in class. At this time, attention is transferred from perception to the inner world.
D. Excellent football players can look up and observe the situation on the field when carrying the ball. At this time, his attention shifted from motion control to perception.
In some cases, our attention may be more focused on the external environment. For example, in a movie theater, a thrilling movie will make us forget our inner troubles, and we do not need to do anything.
Sometimes, our attention is more focused on action control. For example, when practicing driving, practicing a new action in physical education. Or when you give a speech for the first time, you are more concerned about how your actions are completed? The perception of the surrounding conditions will become narrow and fuzzy.
Sometimes, our attention is more focused on our inner feelings. For example, before going to bed, we neither listen nor watch, nor do action, and your attention is completely focused on your experience.
In most cases, our attention is more focused on sensory perception and action control. Compared with our inner feelings, our sensory signals are clear and more attractive to us. Action Control determines the effect of our current work. It forces us to pay attention to it.
Many white-collar workers have the idea that I am too busy during this time and really want to stay alone for a while. From the perspective of attention distribution, he hopes to get rid of the external world and action and focus on his own inner world.
However, once people are under load, their life circles are limited, and there is no information in the external world, they do not need to pay attention to their actions, so they can easily retreat back to their own internal world. These people will become overly sensitive and stunned. Excessive attention is concentrated in the internal world. Many psychological problems come from this cause.
