If you don't comprehend trading, you'll just stare at the market every day, staying up late, while you yourself don't know anything. You're constantly watching the fluctuations of your account funds, getting scared when the spot falls a bit, wanting to sell when it rises, and rushing in to chase the price. Your emotions are always being led by the market; emotions are like inner demons. If you don't control them, they will consume you. Hope, greed, despair, fear, impatience, ignorance, and laziness are your biggest enemies on the trading path.

The reason why profitable people make profits is that they focus on how to avoid losses. The reason why losing people incur losses is due to impatience, fantasy, and assumptions.
The most important thing in investing is to protect your principal. This is something that the second brother may have said to you the most. Before seeking victory, you should first consider failure and come up with a two-way response strategy. What should you do if you make the right call? How should you respond if you make the wrong call? The direction of your thinking should be to first correct the habits that lead to your losses, and then improve your ability to profit.
The nature of trading is gradually worn away; after suffering many losses, even when profitable opportunities are right in front of you, you dare not act. The emotional stability of a trader reflects their ability and their cognitive framework. Learn to think in probabilities, accept that losses are just a norm, let go of fantasies of sudden wealth, and break the gambling mentality. Only trust your own signal system; it doesn't matter if you don't understand the market, what matters is understanding your own rules.
Become an emotional insulator, execute like a machine, buy what should be bought, sell what should be sold, without entanglement or hesitation. True stability is not about defeating the market, but about taming human nature. Cultivate and establish your own trading system; there should be a distinction between spot and contracts. I always say that people cannot earn money beyond their own understanding; money earned by luck will ultimately be lost. Everyone has their own fate; in fact, some things are already predetermined the moment you participate. Many people say it’s all fate when they fail, but I believe that while fate is predetermined, it is not absolute. Second Brother believes: "Fate is determined by heaven, but fortune is in one's own hands"; this is also why some can survive even in desperate situations, while others live their lives in mediocrity.
