Do the famous words of “Sun Tzu’s Art of War” prove that many people do not know themselves?

Famous words in “Sun Tzu’s Art of War” is “If you know your enemy and know yourself, you will not be a fool in a hundred battles”.
Winning all 100 battles is impossible in reality, so how difficult it is to achieve this quote… perhaps this is a testament to that fact.

The fundamental foundation for growing and maturing as a coaching coach is to aim to establish a “self-base,” and the first step toward this goal is to “know yourself objectively.
The first step to this is to “know yourself objectively.” This involves asking “How do others see me? Do they understand you?” is indispensable. Let me introduce the “Johari Window,” which is useful for considering this perspective.

ジョハリの窓

When organized in this way, it seems to lead to an understanding that becomes clear: “I see….”
This chart shows that even if you think “people know you,” the way they perceive you is only one part of the whole. And one can imagine that each person’s four windows will be different in size.

The coaching coach aspires to increase the area of the “open window,” which is the“ Ⅰ window”. This is achieved through self-disclosure and by listening, asking questions, and giving feedback in a serious attempt to understand others.
Likewise, through this process, the space where “self-concept and experience coincide” can be felt to be expanding.
