Sure the stories are fine, and there are some interesting takeaways about arguments in the first few chapters, but the further you get into the book the more it becomes about Seo telling us about debate and his life with little connection to the chapter titles and the purpose of the book.

The best point is that when you get into an argument stop and define what you're arguing about. It's far to easy to ramble around into many unrelated areas if you don't define the point of the argument. This is very common the closer you are to someone as you let the argument devolve into anything that's ever gone sideways at any point.

Instead, stick to the point of this argument.
