Investment isn't about chasing the explosive profits of the fish head, nor the last wave at the fish tail, but steadily eating the safest middle section of the fish body. Earn money within the scope of your own understanding, don't gamble on market movements you don't comprehend, and don't chase opportunities beyond your judgment. Hold the line, avoid greed and impatience, and always put capital safety first. When there are profits, lock them in promptly without agonizing over earning more or less, and never regret selling too early or too late. When your mindset is stable, your rhythm becomes stable. Protecting profits and controlling risk is more important than sudden wealth. Long-term and steady growth is the real victory.
