"Colonel Dave Robinson, USMC (Ret) has written an exceptional 'how to' on leadership - something I believe he is eminently qualified to write about. Dave earned a sterling reputation as a fighter pilot, thinker and doer throughout his career - but it was his leadership that truly stood out to me. Thoughtful, principled, hands-on servant leadership was something Dave gave to his Marines and their families every day. It was a joy and an honor to serve alongside him. Anyone can benefit from reading this book - myself included. I enthusiastically recommend it."
