Whether you’re writing nonfiction, memoirs, or novels, the question isn’t just, “Is this a good idea?” It’s “Is this the right book idea for me, this audience, and in this moment?”
Most serious authors don’t struggle with creativity. They struggle with choosing the right idea to prioritize.
You may have multiple ideas that feel meaningful, viable, even exciting. You might already be drafting one of them. And still, a quiet question lingers in the background: Am I investing my time in the right book—or just a good one?
The thing is, even a really good book can flop in the marketplace when it isn’t positioned well. And a book that sells well can still fail to translate into strategic success (bringing you the kind of leads or opportunities you want) if it’s the wrong book. If your focus is simply on selling one book at a time, you’re missing out on a broader range of opportunities.
This matters more than most people realize when you’re trying to choose the right book idea. The wrong book can cost you years of effort, energy, and confidence—again, not because it’s bad, but because it’s misaligned.
Why a “Good” Book Idea Isn’t the Same as the Right Book Idea
A good book idea is interesting, thoughtful, and potentially publishable.
The right book idea is aligned with your goals, your audience, your authority or perspective, and your timing.
The difference isn’t about quality or worth. It’s strategic.
A good idea can still be the wrong choice for this season of your life, your career, or your creative trajectory. And the right book often feels clearer, steadier, and more focused—even when the work itself is challenging.
The diagnostic below is designed to help you test whether you’re working on the right book idea before you invest more time and energy.
The Right Book Diagnostic: How to Tell If You’ve Chosen the Right Book Idea
Read each section and answer honestly. You don’t need perfect answers, but you do need clear ones to get the most helpful results.
1. Goal Alignment: What Should This Book Make Easier?
Start here, regardless of genre or category. Choosing the right book idea always begins with purpose.
Ask yourself:
- What do I want this book to do after it’s published?
- How will choosing the right book idea change what’s possible for me next?
- What should be easier because this book exists?
For nonfiction authors, this might include:
- Clearer authority and positioning in your field
- Better-fit clients, speaking opportunities, or partnerships
- A focused foundation for your platform or services
For memoirists and novelists, this often looks like:
- Establishing a clear voice or thematic territory
- Entering or strengthening your position within a genre
- Building an audience for future books
If you can’t articulate the role this book plays in your larger writing life, that’s a sign the idea may need refinement.
2. Audience Clarity: Who Is This Really For?
Every book—fiction included—makes a promise to a reader. With nonfiction, it’s usually explicit, as in, “This book will help you…,” while creative narratives tend to be more implicit, promising an experience but also engagement with certain themes or ideas through the expected tropes of the category.
Ask yourself:
- Who is this book for, specifically?
- What does this reader want, need, or hope to experience?
For nonfiction, this often centers on a problem, decision, or transformation.
For memoir and fiction, it’s about resonance:
- What kind of reader will feel seen or captivated by this book?
- What do they expect to see happening in these pages?
- What shelves, comps, or conversations does it naturally belong in?
If your answer is “anyone can enjoy this” or otherwise feels vague, the idea may be emotionally compelling but strategically underdeveloped. You may need to better clarify your book’s positioning and make sure it’s written to market.
3. Authority Fit: Why You—and Why Now?
This question can sometimes trip people up, but it’s essential that you can answer it.
Ask yourself:
- Why am I the right person to write this book now?
Authority doesn’t mean ego. It means relevance. There are literally millions of books in print. Why should they choose yours?
For nonfiction authors, this authority may come from:
- Professional or lived experience
- A clear, tested point of view or process
- Readiness to scale and have a wider reach
For memoirists, authority means:
- The unique perspective and detail you bring to the story
- Enough distance or insight to shape meaning your reader can relate to, not just the ability to prettily recount events
- The craft and judgment needed to bring the idea to life effectively
For novelists, authority comes from:
- Deep familiarity with and respect for the genre you’re writing in
- Enough experience as a reader and writer to do the concept justice
If your authority depends on who you hope to become rather than who you are right now, take a pause. A book can be a powerful tool to help you grow your business, but first you need a business to grow.
Consider what steps you might need to take to close the gap and take those steps, whether that means advancing your business a bit more or taking some writing workshops. Smart and creative people often have excellent ideas for books that their current skill level cannot handle. That’s not a failure: While we all know how to read and write, writing a book is a skill set that most people don’t just magically absorb. And doing it at a professional level requires instruction and practice. So if you aren’t there yet, don’t give up—it just means you have a little more work to do.
There’s a famous quote from Ira Glass that describes this particular frustration of new creators–that tension between the vision you have for your creative project and your ability to bring it to life. But the fact that you recognize that gap and can feel that painful tension is exactly what will help you get where you want to go.
If you’ve never read or heard Ira Glass’ statement about the creative gap before, check it out. I think you’ll find it resonates and hopefully inspires you.
4. Structural Viability: Can This Idea Support a Book?
Many manuscripts fail here—not because the writing is weak, but because the concept itself isn’t fleshed out enough, is too muddy, or can’t support a full book structure.
Ask yourself:
- Can I clearly articulate what this book is in one or two sentences?
- Does the idea naturally suggest an arc, argument, or progression?
For nonfiction, the answer should include a clear promise or takeaway.
For memoir, a transformation or organizing lens that speaks to your target readers.
For fiction, a plot engine dressed with genre-appropriate tropes and strong enough to sustain momentum.
If the idea feels compelling but slippery—hard to summarize, hard to organize—it may need repositioning before drafting continues.
This brief one- or two-sentence statement is sometimes referred to as an “elevator pitch” or “sales handle” for your book, and practicing it is a great way to test your book concept. If you’re unable to articulate your pitch in a succinct and compelling way, it isn’t a sign that your story is just too complex to be boiled down. It’s a sign that your book isn’t focused enough to have staying power and isn’t yet marketable.
5. Timing and Capacity: Is This the Right Book Now?
Finally, it’s time to look honestly at your current reality. Many people promise they can help you write your bestseller in a weekend, but the truth is that anything written in a weekend is not ready to be published immediately after. Not if you want to sell and leverage your book successfully.
Remember the old chestnut: Every time you say “yes” to one thing, you’re necessarily saying “no” to another. So if you’re saying yes to the intense process of writing, publishing, and marketing a quality book, what are you saying no to?
Ask yourself:
- Do I have the emotional and practical capacity to do this book justice?
- Does this project align with the season I’m in—or fight against it?
For business owners, this includes bandwidth and priorities. If you’re still struggling to make an income, then your attention should probably be on refining and selling your offers. If your business is expanding and you’re stretched thin, concentrate on your team and systems to free up your resources for a book in the future.

For memoir and fiction writers, emotional readiness matters just as much as time. Writing has proven to be incredibly helpful in processing emotions and trauma, but your journal is not your book draft. Writing for therapy is different from writing for publication; you must be emotionally ready to treat your book as a product and receive objective feedback to help it reach its fullest potential if you’re serious about publishing successfully.
Ultimately, writing, publishing, and marketing a great book is a huge investment of time, energy, and money. Make sure now is the right time for you to make that investment. And don’t feel bad about it either: Choosing “not now” is a strategic decision, not a failure. It’s the difference between procrastinating and prioritizing.
Interpreting What You Found About Your Book Idea
As you review your answers, notice patterns.
- If most of your answers feel clear and confident, you’re likely working on the right book idea.
- If several answers feel fuzzy, the idea may be good but needs refinement.
- If your answers actively conflict, the idea may belong in a different form, genre, or season.
None of these outcomes mean you’ve done something wrong. They simply point you toward better alignment.
What to Do Next If You’re Unsure About Your Book Idea
If this diagnostic raised questions, that’s a good sign. Clarity isn’t something you magically arrive at—it’s something you build, usually with the right guidance and feedback.
If you’re early in the process or feeling uncertain about direction, your next step isn’t to write more. It’s to get clear.
Two good options, depending on where you are:
1. Book a Positioning & Publishing Plan (PPP).
This is where we pressure-test your idea, clarify your audience and promise, and make sure you’re investing your time in the right book—not just a good one. It’s designed specifically to prevent wrong‑book syndrome before it costs you months (or years). You’ll come to understand how many downstream decisions are informed by your goals for the book and walk away with a comprehensive publishing plan.
2. Watch the “Don’t Write the Wrong Book” webinar.
If you’re not quite ready to work together yet, this free 25-minute workshop walks you through a five-step process for further aligning your book idea with your goals so you can sanity-check your concept before moving forward.
Either way, the goal is the same: clarity before commitment.
A Final Thought on Choosing the Right Book Idea
Choosing the right book is an act of respect—for your reader, for your time, and for yourself as a writer.
Looking around at what content you have that you can randomly pull together and publish isn’t going to get you a book that generates repeatable results for your business. Neither will transcribing all your past talks just to “get something out there.”
The right book doesn’t always feel easier to write. But it does feel steadier. More intentional. More aligned with who you are and where you’re headed. Your ideas will gel more easily, and the writing process will feel a lot less like a struggle and a lot more like flow.
Publishing success doesn’t start with drafting. It starts with choosing the right book.
