A fundamental difference between living and non-living things is that the former possesses inherent defense mechanisms; otherwise, they could not survive. Therefore, when dealing with living things, if you want to achieve a certain goal, you should try to avoid triggering their defense mechanisms. Otherwise, the more force you exert, the stronger their defenses will become, resulting in a waste of energy. Brute force is only suitable when there is a significant disparity in strength between the attacker and the defender. To move a stone, you need great strength. To catch a cat or dog, the more aggressively you chase them, the faster they run. But if you ignore them, show no interest, and leave food outside, they will come to you and bother you. The tragedy of many people's lives lies in their relentless application of their experience in using brute force to move stones to their interactions with living things. They constantly and quickly trigger the opponent's defense mechanisms, ultimately becoming exhausted and receiving a negative return. Then, in retrospect, they believe they didn't exert enough force and continue to escalate the situation, stubbornly persisting on the wrong strategy.
