A famous trader on Wall Street once said that 80% of his trades are failures, yet he can still achieve stable profits, with profits coming from the 20% that are successful. Although this example is a bit extreme, the principle is the same.
In a person's trading journey, early failures are essential for growth, and later mistakes are inevitably within the range allowed by probability. One must accept failure, embrace stop-losses, and not pursue excessive perfection. Taking one big step forward and a small step back is as inevitable as the natural laws of the universe. Opening a position and setting a stop-loss are two sides of the same coin, and adding a take-profit creates a trinity; without any one of these, success cannot be achieved.
