Theory is just a dissection of reality, but the real skill is in the present moment.
We should not only use the eyes of theory to see the trend clearly, but also gradually make ourselves one with the trend. What is the initial skill of the line? In the final analysis, it is "just right". This "just right" is dynamic. No matter how many people there are, everyone's behavior is regarded as a vector. The behavior of all people eventually constitutes the vector of the trend, and the so-called "just right" is the total vector itself.
And how can we always be consistent with the direction of this total vector? First of all, we must turn ourselves into a zero vector. Only when a zero vector is added to any vector superposition system will it not affect the final total vector direction.
