The essence of trading

is to help you sleep well; otherwise, trading is fundamentally useless,

regardless of whether you win or lose. Its essence is to let you sleep; if you can't sleep, even if you win, you will go crazy, feeling a sense of oppressive tension that drives you to make chaotic actions and ultimately fail. If you lose, and you can't accept this fact, you can't bear it, then it's the same; it will also lead you to make some crazy moves and fail. This is like a theory that is strong in theory; if you don't put it into practice, it will never let you fail, and you will never succeed. But in the end, it still comes down to your own heart. In fact, sometimes losing means that as long as you believe in your heart that you have won, then you have won, because stocks are virtual. If you lose and you believe you have lost, then you have truly lost. So, never let yourself fall into a passive state of believing you have lost, as it interferes with your mind. When your mind has issues, you will make some chaotic actions and then end up completely losing. Many have been trading stocks for years, not lacking wealth, talent, or genius, but they all share one important characteristic: mindset. Everyone has different ways of coping; if your madness overrides your rationality, then you are a genius. If your skills surpass your rationality, then you are a master. If you randomly rely on luck, then you are a talent. Therefore, I believe everything is in the heart; the heart is everything.
