There are only two types of people who can trade well in the stock market:

1. Those who are patient enough to hold a position for years without moving;

2. Those who are rational enough and have a good market sense.

1. Patience comes from experience, self-cultivation, and sufficient financial support;

2. Rationality and market sense can be improved through training, but they ultimately depend on physiological conditions:

Whether a person's prefrontal cortex is well-developed determines their rationality. This can be enhanced through reading, exercise, meditation, and participation in precise social collaboration and leadership.

That's why we often see emotionally intense, highly expressive investors in the stock market who tend to suffer long-term losses. These investors typically care more about their feelings, emotions, or self-esteem, making it hard for them to objectively recognize facts.

The brain's mirror neurons determine introspection and observation abilities—having a clear self-awareness system to observe one's emotions while accurately deducing future trends from complex external information. This part cannot be improved; it's purely innate.

A basic rule of thumb: people with low tear thresholds, strong empathy, and rationality usually have good market sense.

In conclusion, only a few are born with the traits of excellent traders, and ordinary investors are rarely trainable. This is the biological reason why, over the long term, only a minority profit in the stock market.
