This book is just a tool for self-study. It would seem a little over-the-top to discuss such grand topics as "what is knowledge", "what is learning" and "what is the essence of man". But examining the premise and searching for the source is also closely related to practice. These questions not only appear in obscure professional books, but also in the process of learning. Indeed, when we are moving forward smoothly, our eyes are only fixed on the front, not at our feet. When we are serious about doing something, and we encounter obstacles along the way, or find that our efforts are completely in vain, we start to think (or talk to ourselves) "why did it end like this?" "Why do I have to do this". Humans are the first creatures who love to ask "why". It is this nature that drives us to learn and to think about how we should learn. Of course, many questions won't be answered at all, or even listened to, and will just go away on their own. Many times, even if we have doubts, we have to move on and cannot stop for them one by one, otherwise it will be difficult for our daily life to go on smoothly. But the next question I'm going to ask touches on the deep nature of being human and the foundation of learning. Since the purpose of this book is to assist those who want to teach themselves, there is no way around these problems.

Since the purpose of this book is to assist those who want to teach themselves, there is no way around these problems. To answer these questions, I need to first introduce you to Double Process Theory [illustration]. This theory is related to both the acquisition of knowledge and experience, and cognitive abilities such as thinking, as well as non-cognitive abilities such as self-control and patience, allowing us to comprehensively understand human mechanisms.

Two systems theory holds that human cognition and behavior are generated by two systems (processes). System 1 is in a state of unconsciousness and automatically and quickly follows intuition to make actions; System 2 is under the control of consciousness and has a slower reaction speed, which is an action after thinking. We can compare System 1 to a group of traditional craftsmen. I use the word "cluster" because the system contains many different "professional divisions", aka "mods".
