His most recent book is 10 Publishing Myths: Insights Every Author Needs to Succeed.

Terry’s favorite mistake took place in 2007, when a high-profile publishing event jolted him into realizing just how little he was doing to promote his own books. Despite having secured multiple six-figure advances and a long list of published titles, Terry was receiving negative royalty statements—his books weren’t earning out. That wake-up call led him to take what he calls 100% responsibility for his own success, adopting a daily commitment to book promotion, content creation, and building an online presence. From that turning point, he launched a blog (now with over 1,700 posts), grew a substantial social media following, and became a consistent voice in the author education space.

In the conversation, Terry and Mark explore the myths and realities of book publishing—especially the misconception that a publisher will handle marketing. Terry outlines how today’s authors must become active promoters, the importance of building an email list you control, and why giving away ebooks can actually drive print book sales. He also shares hard-earned lessons about evaluating publishers, avoiding scams, and understanding how traditional and independent publishing models differ. Whether you’re writing your first book or navigating your next launch, Terry’s insights are a masterclass in professional ownership and long-term thinking.
