As a long-term investor, one must adhere to the following fundamental principles:
First, protecting principal is always the most important, ensuring survival is the primary task of investing. Second, the future is full of uncertainties; our goal is not to predict every market fluctuation but to capture trend dividends during bull and bear cycles. Finally, avoid taking risks with every market fluctuation, learn to buy and sell at the right time, control desires, and find contentment. This is the true wisdom of successful investing.
