You bought in for 10 yuan;
When the price drops to 8 yuan, you begin to feel anxious;
When it drops to 6 yuan, you decide to hold on;
When it drops to 5 yuan, you become numb;
When it rises to 7 yuan, you are indifferent;
When it rises to 8 yuan, you start to have feelings;
When it rises to 10 yuan, you begin to hesitate;
When it drops back to 8 yuan, you regret it;
When it returns to 10 yuan, you decide to sell;
Then, the price soars to 12 yuan, and you choose to liquidate;
As a result, it continues to rise to 20 yuan, 30 yuan, even 40 yuan. You are stunned, going crazy, seeing those around you making big money, and you can't help but buy at the high.
In the past decade, I've seen 99% of people rush into the market at the top of a bull market, while holding on tightly during a bear market downturn. By the time the next bull market arrives, they almost always sell after recovering their losses, only to re-enter the market at a high once again.
This is the pattern. Patterns represent cycles, and human nature is also a kind of cycle. Therefore, understanding the 'Dao' within is to comprehend the weaknesses of human nature and the cyclical nature of things.
