I spent 96 yuan to print the support system myself, and then spent half a month reading it all. The 96 yuan was worth it. Beating a dog can result in losing a few sol, which is several thousand yuan. However, for books that can improve one's cognition, enhance one's luck, and make oneself more positive, one is unwilling to spend time reading them. There should also be an issue of feedback timeliness here, such as the immediate profit and loss from hitting a dog, which is immediate feedback, while the understanding of book thinking methodology is subjective and delayed feedback, which supports our actions in this circle precisely through methodology and cognitive judgment. How long has it been since you read a book seriously? More than 20 people asked me for the support system before, so I guess they just left it there to eat dust. Only those who have paid the cost themselves will cherish it. Another thing is that these things are all publicly available and can be utilized from:@ Lanxing4 supports the system command to search.
