Retail investors have no control over the market, and the core logic of making profits is simple: lock in high odds opportunities and repeatedly execute a stable strategy. The reason for repeatedly emphasizing this point is that once you try to make the market follow your expectations, anxiety and mental tension will follow you like a shadow. From a neuroscience perspective, long-term high pressure raises cortisol levels—suppressing neurogenesis, accelerating neuron apoptosis, leading to hippocampal atrophy, and triggering inflammation in the prefrontal cortex, making you emotional, impulsive, and causing your judgment to continuously decline. In short, forcing a contest with the market is purely a thankless task, and long-term mental exhaustion will only make you more "get carried away" in trading, making your mind less sharp.
