simple but not easy The way to make money must be: Simple (not complicated), but not easy (difficult). Like many mathematical and physical formulas, the form must be simple and beautiful, and it can be repeated in accordance with reality. However, from the simplicity of the formula itself to the discovery and understanding of its application, there are still thousands of mountains and rivers (not easy).

This leads to two inferences: First, if the way you make money is too complicated, the probability of making mistakes increases, and the path is likely to be wrong. Second, due to investment and speculation, it is extremely difficult to achieve certainty; you must refrain from acting if you don't understand, and clearly know what you don't know.
