Why is trading difficult? Essentially, it is a challenge to human nature. First, making small profits is easy because it aligns with the human tendency of 'locking in gains.'

Many traders, once they see a small profit, are eager to close their positions, fearing a loss of profit. This behavior seems reasonable in the short term but weakens your ability to capture big moves in the long term. Worse still, the regret after a price pullback will further reinforce the mindset of 'running away early,' leading you deeper into the wrong path.

Secondly, making small losses is difficult because it contradicts the 'wishful thinking' in human nature. When prices drop and then rebound, many people start to self-comfort, 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 turn into large losses, with traders being emotionally hijacked and caught in a vicious cycle of avoiding reality.

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

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