The cultivation of investment temperament is a long process, because investment is essentially a dilemma between profit and loss. When we obtain limited profits, we complain about leaving too early; conversely, when we suffer losses, we complain about leaving too late.

So, is it leaving too early or too late? Actually, it's very simple—set strict principle lines for yourself, and you can set multiple types of principle lines. With these lines, you have a benchmark.

When the market fluctuates, no matter when you leave, you will receive positive feedback, and gradually, you will develop a very stable temperament.
