A book does more than prove what you know. Done properly, it forces you to clarify your thinking, test your ideas and turn years of experience into something credible, useful and commercially valuable. For professionals working with sophisticated clients, that depth matters because a thin book can weaken your authority just as quickly as a substantial one can strengthen it. 

Rob Nankervis is an executive coach, leadership team adviser and author of Propelling Performance, a practical book designed for established mid-market businesses that are already good but want to become better. In conversation with Andrew Griffiths, he shares why writing the book became the biggest self-development exercise of his career, how it helped him codify his thinking, and why authority matters in an industry where anyone can call themselves a coach. 

Rob also explores the importance of writing from real experience, building a robust model, understanding a sophisticated audience, and using a book to reinforce speaking, workshops, referrals and long-term client relationships. It is a thoughtful, grounded conversation about substance, credibility and writing a book that genuinely earns its place in the market.
