A rolling stone gathers no moss, and short-term trading does not make wealth. In the stock market, the more one hopes for a big rise tomorrow, the less likely it is to happen; the more one leaves stocks alone without watching them, the more they may grow - even exceeding thirty years of bank interest in just three months. Lin Sheng is such an extraordinary person in the stock market. In his over ten-year career as a stock trader, he has been severely caught in the trap of a bear market twice, with floating losses of more than half each time. However, he firmly believed in value judgment, refusing to cut his losses or liquidate his positions. His steady personality also brought him great rewards, with his most successful times seeing his stock portfolio valued at over 2 million yuan, nearly 40 times his initial capital of 50,000 yuan. He frankly told the reporter that the only belief supporting him throughout his journey was this: every stock purchase is carefully considered, and once executed, there is no regret - he won't sell until he makes a profit, even if he dies.
