In the field of investment, it is often found that one does not fail due to a lack of skills, but rather stumbles on the weaknesses of human nature. This phenomenon is particularly evident during market fluctuations: when the market falls, some investors stubbornly hold onto losing positions, unwilling to implement stop loss in a timely manner; while when the market rises, they rush to take profits out of fear of missing out on more gains.

This psychological pattern of 'unwilling to acknowledge losses, eager to realize profits' is precisely the reason why many investors find it difficult to achieve sustained success in the market. The market rewards neither excessive greed nor sympathizes with indecisive attitudes. Those who hesitate to stop loss when they should are no different from those who knowingly take risks despite the danger; while those investors who easily exit when they should hold on may miss out on important profit opportunities.

Successful trading does not rely on intuition or feelings, but is built on strict discipline. Formulating a clear trading plan and firmly executing it is the key to achieving stable returns in a complex and changing market environment. Investors need to overcome emotional interference and rationally assess each trading decision; whether it is a stop loss or taking profit, it should be based on a pre-established strategy rather than impulsive decisions.

Cultivating good trading habits and psychological qualities is crucial for long-term survival and development in the market. Only by truly understanding and mastering their own psychology can investors remain calm amidst the market's fluctuations and make correct judgments, ultimately achieving their investment goals.
