I thought by the title and the description of the book that it was about running a martial arts school. This is not so. It is a book about how to run a business with the principles he learned from taekwondo lessons. He does talk a lot about himself but it worth reading once for the information. The book does have overtones of you can't run a business properly without a computer and software and he has business software for sale. The last pages of the book are his infomercial for his software. I am glad I did not spend money on this book. I personally think that his lessons are a great starting point if you are looking for information on how to start a small business.
