Got both the books by Jocko Willink for my Son. He love the book as it is very relatable to things all kids face. It's so cool to sit close with them at the end of the day and read about things like the importance of honor, discipline, courage, teamwork, and a moral code.
Fantastic book for kids...Gifted it to my 9 year old niece who loves the Wimpy kid series..This book changed her idea of being a wimpy kid to a warrior kid which is the real life fighter kid attitude...She sees me as Uncle Jack :D
All of the wisdom of Jocko Podcast has been distilled down into this book. I have been working out, eating right because of the discipline mindset Jocko talks about. It is one of the best investments that you can have in yourself. Recommended reading for every human.
