Writing a book always starts with the same struggle: finding the right idea. It’s not a lack of creativity or intelligence that holds people back—it’s the absence of structure. In my work with over 130 aspiring authors, I’ve seen brilliant minds go blank simply because they’re not sure how to begin. They have experience, insights, stories—but no starting point. And without a clear direction, even the best intentions fall flat.
The truth is, brainstorming a book isn’t about throwing ideas at the wall and hoping something sticks. It’s about identifying a gap—something your audience is missing—and making a statement—a bold, memorable idea that fills that gap. This process doesn’t just help you come up with a book idea; it lays the foundation for a book that’s purposeful, relevant, and aligned with your expertise.
Before pen meets page, you need clarity. You need a framework that brings your knowledge and your audience’s needs into alignment. That’s what this article is about—giving you the exact method I use with clients to turn vague thoughts into structured, sellable book concepts.
Most people treat brainstorming like a burst of inspiration. But if you want to write a book that matters, brainstorming must be methodical. It’s where strategy meets creativity. This is the phase where you lay the foundation of your book’s structure—not the chapters, but the very essence of your thinking.
In The Architecture of Writing, I explain that every book needs internal alignment before it gets external expression. You need to know who you’re speaking to, what conversation you’re joining, and why your voice deserves to be in the room. Otherwise, you risk writing a book that sounds smart but says nothing.
The real purpose of brainstorming isn’t to find any idea—it’s to find your idea. That means uncovering a gap that matters and creating a statement bold enough to carry a whole book. Everything else—title, chapters, outline—will come more easily once this thinking is clear. Without this foundation, you’re building on sand.
Every meaningful book begins with a gap.
A gap is what’s missing in your field or in someone else’s understanding of it. Most authors overlook this step. They write what they know instead of writing what’s needed. But what makes a book valuable is its ability to fill a void—not repeat what’s already been said.
There are two types of gaps you can address: one within your field, and one outside your field. If you’re contributing to your field, look at what’s been overlooked, misunderstood, or outdated. Are people repeating flawed ideas? Is there a missing piece no one’s dared to touch? That’s your opening.
Is there something currently missing in your field? Or is something off? The people in your field form a community, and, together, they are having a conversation. However, groups don’t think as well as individuals—it’s a flaw in human nature. It’s possible that the group is missing something crucial or is making a mistake.
You can contribute to your field by writing about what is missing or which mistake is being made. Remember, the point of writing and reading is to further our understanding of the world. Don’t make the mistake of trying to find something just for the sake of it, or else you risk alienating people in your field.
If you can’t find a way to contribute to your field, you can turn to teaching other groups of people.
Academic writing is a great example of contributing to a field. The purpose of writing a thesis is to bring to light new findings or a new perspective. That being said, you can contribute to your field outside of the academic world. For example, if you’re an investor, you could write a book on a concept or method you’ve created to fill a gap in your work.
The beautiful thing about the world is that we can all contribute to each other’s lives with our expertise. For example, my primary field of expertise is writing. I can talk about writing to different groups because writing, just like your expertise, can benefit anybody.
If you’re going to teach other groups in a different field of study, you need to pick one group and be smart about it. For example, I could pick entrepreneurs because they’re my favorite people. As an aside, it’s not advised to pull your focus by writing more than one book at a time because you won’t be able to adequately attend to your group.
Once you’ve chosen your group, you need to find what gap they have when it comes to your field. In my case, the gap I’m filling is that entrepreneurs know publishing a book is good for business, but they don’t know how to go about it. So, I should write about how to make writing easier.
Finding the gap gives your book relevance. Making a statement gives it power.
A statement is a short, bold idea that answers the gap you’ve identified. It’s not a summary of your content—it’s the heartbeat of your book. It’s what people will quote, argue with, or remember long after they’ve put the book down.
Too many aspiring authors think their book needs to say a lot. It doesn’t. It needs to say one thing well. Everything else—chapters, examples, frameworks—serves that one central idea. Without a statement, your book becomes a series of thoughts instead of a coherent message.
When I work on my current writing project, The End of Nonsense, my statement is simple: The real divide in society isn’t political—it’s between those who believe in politics and those who believe in personal development. That idea anchored the entire book. It gave shape to every chapter. It also sparked conversation—because it was direct, surprising, and repeatable.
Your statement doesn’t need to be provocative. But it does need to be memorable, specific, and clear. It should feel like something only you could say. Once you have it, you don’t just have an idea—you have a mission.
Most brainstorming advice feels like guesswork: make a mind map, journal your thoughts, wait for inspiration. That’s not how professionals approach book development. If you want a process that works, you need to combine structure with freedom. The right brainstorming method leads you from confusion to clarity—fast.
Start by listing the gaps you see in your field. These could be myths people believe, questions no one’s asking, or problems with no clear solution. Then, shift focus: What misunderstandings or missing knowledge do people outside your field have? Both lists will reveal opportunities.
Once your gaps are clear, generate as many rough ideas as you can. Don’t filter. Use bullet points. Raw is fine. Then begin distilling: Turn those ideas into statements—short, punchy sentences that make a claim or offer a perspective. Reduce, refine, and prioritize.
Your strongest statement becomes the core of your book. The rest become chapter ideas or section headings. From there, brainstorm supporting arguments, case studies, or frameworks for each point. You’re no longer guessing—you’re building.
This is how I guide clients through the earliest stages of authorship. Not with vague brainstorming, but with structured ideation. Because when you organize your ideas this way, writing doesn’t just feel easier—it becomes inevitable.
Once you’ve identified your gap and clarified your statement, you’ve already done more thinking than most aspiring authors ever will. But you’re not finished. Now it’s time to structure your book into something you can actually write. Think of this as turning raw story ideas into a blueprint.
Take your central statement—the bold idea your book revolves around—and treat it like the sun in a solar system. Every chapter should orbit around it. Use your secondary statements to form a table of contents. These become your chapters or major sections.
Under each chapter, brainstorm specific short story examples, frameworks, questions, or takeaways. This is where your knowledge turns into structure. Bullet points work well here. Don’t worry about full sentences—focus on building a scaffold that supports your message.
This approach makes it easy to start writing. You’re not just staring at a blank page—you’re following a clear, strategic outline. And because that outline is rooted in a real gap and a strong statement, your book will feel cohesive from start to finish.
Here’s the truth: most people skip the hard part. They don’t slow down long enough to find the starting point. They jump straight into writing with a “good idea,” only to lose steam halfway through. Why? Because the idea was never anchored in a real need.
People confuse trends with gaps. They think being passionate about a topic is enough. It’s not. A book isn’t just self-expression—it’s service. If it doesn’t close a gap or deliver a statement, it’s just a journal entry.
Another common mistake is overcomplicating the brainstorming technique. Some people chase endless frameworks or prompts hoping to stumble on clarity. But the power is in simplicity: list different ideas, distill them into statements, and choose the one you can stand behind for 40,000 words.
Strong books aren’t built on excitement. They’re built on alignment—between your experience, your audience’s needs, and your core message. That’s how you go from new ideas to a book that leaves a mark.
Most aspiring authors treat brainstorming like a warm-up. But if you approach it as a craft, it becomes the foundation of a meaningful, publishable book. Story ideas aren’t enough. What matters is identifying a gap worth closing and crafting a statement that cuts through the noise.
As a writing coach and ghostwriter, I’ve seen this process turn scattered thoughts into clear, marketable books. Not because we got lucky—but because we followed a system. When you treat brainstorming as strategic thinking, you stop waiting for inspiration and start building momentum.
So if you’re stuck, don’t ask, “What should I write about?” Ask, “Where’s the gap, and what’s the statement I can make that no one else can?”
That’s how you stop staring at a blank page—and start writing a book that matters.
