Most of the dry goods in today's society are like the operation manual for the workers on the assembly line. This screw is turned 6 and a half turns, and the nut is turned 3 turns. If you think in a black box, you don't think about why this screw is screwed 6 and a half turns and the nut is screwed 3 turns. , once you encounter a new screw, you have no way of knowing how many turns the screw has been turned on. At present, most people want to see dry goods and practical exercises that can be implemented. This is no problem, but if you only want to see practical dry goods and only use black box thinking, then you can't actually put such dry goods. Apply the content to your own work.
This is what the high school math teacher said, one will learn it once and one will make mistakes. It is easy to write the answer according to the answer, but it is difficult to write the answer according to the question. Every conclusion has its premises and assumptions. If you abandon these and only look at the conclusion, it is tantamount to seeking a sword in a boat. From this perspective, in fact, the conclusion may not be important, and the process of own operation and practice is the most important. Therefore, dry goods and cognition, which one should you promote vary from person to person and from the perspective of looking at the problem.
If you need dry goods, you need to distinguish the "authenticity" of dry goods, and avoid falling into the trap of "seeing is learning and even doing it", and more is to use black-box and white-box thinking to rationalize choice. The reason for discussing this issue is to tell everyone that the dry goods that are within your reach may not be as valuable as they seem. One article or several articles, or even dozens of articles, are essentially others. The pieces of information that have been chewed out are pieced together, but the real value may need to be obtained through reading and thinking over a long period of time, thus forming our cognition and affecting our every decision.
