In response to this question, I also asked Mr. W, who shared his own method: classify the books he read according to the system he formed for himself. For example, Mr. W's two systems of recognizing and looking at the world at present are life algorithm and life Beidou. Take the life algorithm, for example. His life algorithm has formed six folders for his books: system A, communication ability, leadership, project strength, professional empowerment, and underlying logic (time, probability, and cycle), so that if he thinks that the books he reads correspond to these six folders, he can put them in. If he finds that they are not related, he can create corresponding folders according to his different interests.
I find that the advantage of doing this is that you classify the books you read according to your systematic tools to understand the world. When you want to call them, you can applaud and follow your own logic. At the same time, it will form a corresponding storage in your mind, just like a library classifies different books accordingly.
I feel that for myself, the book classification at this stage can also be carried out according to this logic, according to the bottom logic of system A, system B and life algorithm, and then this is subdivided according to the subdirectories inside, and the professional empowerment in system B is carried out around human resources. Similarly, I think I have a very important thing to do at this stage: I need to read widely around the theme of human resources!
Therefore, the classification of reading should be based on your cognitive logic of the world. If you classify according to the library, you will feel almost nothing!
