The main reason for this is that we are all human. And most people tend to do the same. Therefore, there is such a science as psychology. Psychology explains well why most people do the same in similar situations. We are all subject to certain emotions that prevent us from becoming successful. For example, fear, greed, impatience (what you are talking about). Many emotions come from our limbic system. That is, these are basic emotions that arise when a person is in a certain situation. But in addition to the limbic system, modern people have the cerebral cortex, so we can try to control all emotions. And when a person learns self-control, it will bring him to a new level in trading. Just don't need to think like the majority. Always try to think like a whale!
