In the book, Zack learns it can't hurt to try until you succeed as he learns the enjoyment of trying and its results.

Over the years, Sensei Jason has heard from parents looking to enroll their child into karate that they want their child to gain confidence and learn discipline and respect. This book is his answer to those parents. As a child learns to try and try again, they learn they can do it, and parents will see their child's confidence grow. Sensei Jason also tells parents to use that same principle of trying their best each and every day to help grow overall in life.
