A father wrote a journal because he thought he might die. This companion guide examines the principles that journal contains — and shows you how to live by them.
In 1990, Major Mark Hertling opened an army-issued green notebook in the Saudi Arabian desert and began writing to his two young sons. His cavalry squadron had been told to expect casualty rates above fifty percent. The journal was his way of ensuring that if he did not come home, his boys would know their father — his values, his fears, his love, and the lessons a lifetime of service had already taught him.
Hertling survived. He went on to command the United States Army in Europe, lead thirty thousand soldiers through the Iraq surge, build leadership programs in healthcare and academia, and spend a decade as a national security analyst for CNN. Decades later, his journal became the published memoir If I Don't Return: A Father's Wartime Journal — a rare, unfiltered account of what a soldier believes matters most when everything else might be taken away.
This companion guide takes those beliefs off the page and puts them to work in your life.
Across twelve chapters organized in three parts, If I Don't Return and Mark Hertling's Thoughts examines the major themes of Hertling's journal and career — from the physiology of fear and the compound nature of character, through combat leadership and the bonds forged in shared hardship, to the challenges of reintegration, the translation of military leadership to civilian life, and fatherhood as the longest and most consequential mission of all.
What you will find inside:
Why preparation — not fearlessness — is the foundation of genuine courage. How character operates on a principle of compound integrity, built through thousands of small decisions no one else sees. Why the most dangerous decision in a high-stakes environment is often no decision at all. What military brotherhood teaches about building deeper civilian relationships.
How humility functions as a leadership multiplier rather than a concession. Why grief must be carried honestly — neither suppressed nor surrendered to. How to translate hard-won leadership principles across careers, cultures, and life chapters without abandoning the convictions that make them effective. And why the most durable legacy is not a set of finished answers but an ongoing, honest conversation between generations.
This book is for veterans and service members who recognize their own experience in Hertling's words. It is for leaders in any field who want to ground their practice in principles tested under the most demanding conditions imaginable. It is for fathers and mothers who understand the weight of wanting to pass something meaningful to their children. And it is for anyone who finished If I Don't Return and asked the question that matters most: How do I actually live this way?
The journal began as one father's message to two young boys. This guide extends that message to anyone willing to engage with its questions — and to begin writing their own answers.
