In Duan Yongping's interview, he responded to a very interesting question: Is copying homework sustainable?

His reply was quite heart-wrenching: It is impossible to sustain. Firstly, even Buffett makes mistakes. Secondly, copying homework is lagging; by the time you notice it, others have already profited, and only then will you pay attention.

Most importantly, the positions in copying homework are not synchronized. How can your position possibly match exactly with someone else's every operation?

In the end, this will lead to different results. Therefore, you can learn and make it your own, but it is impossible to follow any one person's strategy and replicate it one-to-one to continuously achieve results and reach wealth goals; this is impossible. #段永平
