Book excerpt: Mentoring matters! It matters because it shapes both the present and future of our Army. It matters because at our core, we are social beings who need the company of one another to blossom. It matters because, as steel sharpens steel, so professionals become more lethal and capable when they can feed off one another. This book is all about the lived experience of mentoring for Army officers. Within these pages, you will read real stories by real officers talking about their mentoring experiences.
