Every book exists in a market. The writer who ignores this, who believes that quality alone will find its audience, is working significantly harder than necessary and producing unnecessarily uncertain outcomes. But every book worth writing also exists in a conversation, and the writer who is entirely driven by market considerations ends up producing something technically correct and fundamentally hollow. The books that work commercially and endure are almost always both things: strategically positioned and genuinely necessary. The writer found the intersection between what the market needed and what only they could provide.
The Intersection Question
The question I spend the most time with at the beginning of any new project is: what is the thing I can write that nobody else can write in quite this way? For Somatic Productivity, the differentiation was the bridge between two conversations that had been kept apart: the productivity conversation, which largely ignored the nervous system, and the somatic therapy conversation, which largely ignored the working context in which nervous system dysregulation most commonly presents. No existing book was standing in that gap. That gap was the book.
For High-Functioning Burnout, the differentiation was the specific population, high performers who are still functioning, who have not crashed, who are invisible to the burnout literature's primary focus on those who have. That population was underserved. The book served them.
“The book worth writing is the one that closes the gap between what the conversation needs and what only your specific combination of experience and perspective can contribute.”
The Reverse-Engineering Method
One practical method for finding the unique contribution is reverse-engineering from the gap. Start not with what you know but with what is missing. What conversations in your field are incomplete? What needs are not being met by the existing literature? What population is underserved? This requires genuine engagement with the field rather than familiarity with it. The writer who knows what books exist in the space they are entering, who has read widely rather than skimmed, can identify the gaps more precisely.
In Parenting the System, the gap was structural: the existing literature addressed either the clinical end, parents of diagnosed children navigating formal SEND provision, or the general end, standard parenting advice that assumes neurotypical development. The enormous middle ground, parents of teenagers who are clearly struggling but who do not yet have a diagnosis, navigating a system that requires labels to unlock support, was largely unaddressed. That gap was the book.
Why Only You
The answer to 'why only you' is not that you are uniquely brilliant. It is that your specific combination of professional experience, personal proximity, research engagement, and the particular frameworks you have developed sits at an intersection that nobody else occupies in quite this way.
For me, that combination is: nine years of professional training across multiple industries with over six thousand people; several years in SEND educational support working at the sharp end of behaviour complexity; sustained engagement with neuroscience, polyvagal theory, somatic therapy, and systems thinking; and the experience of having built and collapsed a business, relocated countries, and rebuilt. None of those alone would produce the books I have written. Together, they produce a perspective I have not found anywhere else. Your combination is different. But you have one. The work is in identifying it precisely enough to know what book only you can write, and then writing it with enough conviction that the reader who needed it knows they have found it.
