BTB 154: Mark Divine on Unbeatable Mind: How an Author Sold 300,000+ Books, Navigated Self vs Traditional Publishing, and Built a Lasting Platform

Before the Bestseller


Today we welcome back Commander Mark Divine, a man who has led Navy SEALs, built multimillion-dollar training companies, and sold hundreds of thousands of books, to unpack the real story of what it takes to write and market a bestseller. Mark is not only a retired SEAL Commander but also the founder of SEALFit and Unbeatable Mind, programs that combine elite physical training with mindfulness, breathwork, and visualization. His books, including 8 Weeks to SEALFitThe Way of the SEALStaring Down the Wolf, and Unbeatable Mind, have earned spots on both the New York Times and Wall Street Journal bestseller lists while inspiring leaders, athletes, and readers around the world.

In this episode, Mark takes us behind the scenes of his author journey, from the unexpected phone call that led to his first publishing deal, to the freedom and higher royalties of self-publishing, to the tough decision to return to a traditional publisher during COVID. He opens up about the financial trade-offs, the hits and misses of building a business around his books, and the strategies that helped him grow a loyal audience. We also get into the practical side of book marketing: how to use podcasts as a launch tool, why audiobooks now drive nearly half his royalties, and the importance of keeping your content simple, consistent, and authentic.

This episode is an unfiltered look at discipline, setbacks, and the lessons that make or break an author’s career. By the end, you’ll see what it really takes to keep moving forward when the odds are stacked against you.
