I spent a lot of thought in order to write this book, every day in addition to class, is in the code word, I am sick in the code word, on the holiday in the code word, is to break up with my girlfriend, I still maintain two more every day, to now 600,000 words, the results are also very dismal, I don't ask for many grades, you at least leave me a word, tell me you are optimistic? As long as one person is reading, I will write it for that person, I haven't stopped a day since I started the book, and I hope that from tomorrow onwards, one of you will tell me, you are reading, okay?
