From dialectical analysis, it is necessary to write about the self, not the external space and environment.

From the source can be analyzed like this:

Even if you put me in a matchbox, I am the master of infinite space. Matchbox and infinite space refer to the outside.

In space and environment, the meaning of famous sayings means that no matter what kind of environment and background I am in, I will be influenced by outsiders.

Dominate and influence, I will still dominate myself and dominate foreign things. Note that man is also an environment.

② "And the most important thing is whether you can become a real master." There are two points to emphasize. The important thing is whether you are in office or not.

In any case, you must dominate yourself: on the contrary, if you can't dominate yourself, it becomes secondary. The ego will be dominated and dominated by the environment and external things.

Therefore, this paper has an appropriate intention: to dominate the self, to be the master of the self, and fate to dominate the self.

Respond to pressure, be the master of the environment, eliminate interference, stick to yourself, create room for growth and create your own life …

Sunshine, grasp your own life direction (navigation mark) and so on.
