Why is trading difficult? Essentially, it is a challenge to human nature.

First, small profits are easy to achieve because they align with the human tendency of 'securing the gains.' Many traders, as soon as they see a slight profit, rush to close their positions, fearing a reversal of their gains. This behavior seems reasonable in the short term, but in the long run, it undermines your ability to capture larger market movements. Even worse, the regret from price pullbacks can further reinforce the mindset of 'running early,' causing you to sink deeper into the wrong path.

Second, small losses are hard to manage because they contradict the 'wishful thinking' in human nature. When prices drop and a rebound occurs, many people start to comfort themselves, hoping that 'if they wait a bit longer, they will break even.' This hesitation makes it difficult to set stop losses, and small losses eventually evolve into large losses, with traders being emotionally hijacked, trapped in a vicious cycle of avoiding reality.

The result is: frequent small profits combined with occasional large losses lead to long-term account deficits. In contrast, true experts do the opposite—they dare to accept small losses and patiently wait for significant profits, forming a positive profit-loss structure.

Trading is not difficult in terms of technique, but it is difficult in terms of human nature. Only by overcoming desire, greed, and fear can one achieve maturity.
