The fluctuations of emotions are often influenced by external factors, and even feelings of excitement and joy should be moderated, because behind excitement lies disappointment, and the opposite of beauty is desolation. Only by striving to not be elated by external events or saddened by personal circumstances can one achieve a state of equanimity; otherwise, in the trading market, fluctuating emotions can be extremely dangerous, and even fatal at unexpected moments. The significance of drawing lessons is that even without personal experience, one can gain an immersive understanding, because the nature of thought is leap-like, unbound by time and space. Too often, the cost of personal experience is heavy and immense, so those who are good at drawing lessons can not only gain equivalent psychological experiences but also avoid incurring meaningless costs. However, when emotions suddenly surge, can you truly maintain that clarity?
