Attention is the real bargaining chip we have. As a scarce resource, the load of everyone's attention is very effective. Most failures and misfortunes actually come from the "locking up" of attention resources. The absolute value of the stock decline is not enough to completely defeat a person. Excessive attention to one's own stocks and lack of energy to experience the overall rhythm of the market, thus getting lost in independent small market conditions, are the real reasons that eliminate investors. The same is true in life. Everyone will encounter rubbish things or rubbish people who come to bother and bother. These things often have no positive or long-term value. In this case, every minute and every second you invest is a waste. You must learn to stop losses with attention, and then you will not be too bad at anything you do.
