I've been struggling whether to keep posting. To be honest, the book is almost finished, but it is being revised and sent out at the same time. Looking back, the final draft was very different from the original draft. I knew that only a handful of people were reading this book, and out of respect for them, I insisted on sending two volumes. The main reason for the lack of readers is that I don't have time to promote. If you promote it, the results should be better. I'd like to hear the opinions of the judges.
