I've Been a Bit Calvin Lately, and I Didn't Write What I Wanted to Write.

I’ve been a bit lazy lately, I’m not good at writing scientific and technical articles, I have good ideas, I couldn’t write what I wanted to write, I wrote and deleted, and I deleted and wrote, but I am not satisfied. In the past two days, I have only followed one chapter, and I will start to make up later, and I owe two chapters first.
