Luck is the culprit for increasing risk, while hesitation is the culprit for missing opportunities. If the long line is gold and the short line is silver, then the band operation is diamond. Patience is the key to victory, confidence is the guarantee of success. Those who are willing to fight will not be good at it, and those who are good at it will not be good at it. With enough patience and courage to seize a once-in-a-lifetime opportunity, the harvest will also be unprecedented. Reasonably view market fluctuations, calmly face account fluctuations, survive in the market, do not attempt to profit at all times, just to not miss opportunities and dividends brought by trends.
