To do things alone, you need to have the spirit of "being true". "Drilling to the top of the bull's horns" is often not a bad thing. You can explore the underlying logic of doing things by constantly breaking the casserole and asking to the end. When you do things on the surface, you will never explore the true meaning of things. We have heard of successful "masters" and "experts", but most of them are a little "paranoiac". Putting aside selfish thoughts and desperately seeking truth, you will do one thing to the extreme, which is also becoming an "expert" the only way to go.
