Most investors fail not because of their initial choices, but due to an unstable mindset. Excessive panic when the market falls and blind greed when it rises often lead to losses due to emotional decision-making. The real problem is that many people never build their own investment logic system. Successful investing requires rational analysis, clear thinking, and strong execution, rather than going with the flow. Establishing your own investment framework and maintaining emotional stability is essential for achieving long-term gains in a fluctuating market. Price fluctuations are merely the norm of the market; the key is how to respond to these fluctuations and profit from them.
