1. Apart from mathematics, our Shen Wei basically has nothing that interests him. Besides mathematics, mathematics can greatly concentrate his energy.
2. The ultimate focus, the ultimate focus, can create the ultimate expert. Shen Wei liked mathematics since he was a child, so he devoted himself to studying mathematics, with a high degree of concentration and a long time, which made Shen Wei.
Ordinary people can't do this. Ordinary people have many desires, but Shen Wei doesn't. He doesn't care about face and famous brand. As long as he can meet his physiological needs, he doesn't care about many things. Because he doesn't care about too many things, many people think that Shen Wei's lectures are terrible, and he is talking about himself. There is no interaction in class. I don't know if you understand. This is also because he doesn't care, which leads to many problems, but most of us care about these things.
