What Book Should I Write? How to Choose the Right Book for Your Business

Quick answer: Write the book that best supports the business you're building right now. The right book solves a specific problem for a specific reader and naturally leads them towards working with you. Instead of asking "Which book could I write?", ask "Which book would create the biggest opportunity for my business today?"

If you're a business owner, I'd bet you have more than one book in you.

As entrepreneurs we're often multi-skilled and multi-passionate. That's brilliant for business, but it can be a nightmare when you're trying to choose a book. Every idea feels connected to every other idea. So you overthink, you stall, and the book stays in your head.

The challenge isn't coming up with ideas. It's choosing the right one for where your business is today. So let's make that choice feel simpler.

Why is choosing a book so hard for business owners?

Usually because you're trying to choose between ideas without a clear way to measure them.

Not every book idea serves the same purpose. Some books generate leads. Some position you as an expert. Some support a signature programme. Some create speaking opportunities or build a movement around a message. A book can be brilliant and still be the wrong book for your business right now.

That's why I always encourage people to start with the business, not the book. Once you know what you're building, you have something to measure every idea against.

What's the difference between a book topic and a book concept?

This is where lots of people get stuck, so it's worth slowing down here.

A topic describes what your book is about. A concept defines what you're known for. It brings your specific perspective to the topic.

• Leadership is a topic. Helping new managers become confident leaders in their first 12 months is a concept.
• Marketing is a topic. Helping service-based business owners attract clients without relying on referrals is a concept.

Two people can write about the same subject and create completely different books, because their concepts are different. Readers aren't looking for more information. They're looking for clarity, direction and a way of thinking they can trust. Your concept is what gives them that, and it's also what makes you memorable.

What are the main types of business book?

If you're not sure which direction to go, it helps to know the four types of concept that work particularly well for experts and business owners. One will usually stand out.

1. The method or framework book

You share how you think and the process you take clients through to get a specific result. Lots of experts already have a method they use every day, they just haven't written it down clearly yet. This type of book builds real AUTHORity® because it positions you as the originator of an approach rather than simply a service provider. (If this is you, read my post on turning your signature method into a book.)

2. The problem-solving book

You focus on one specific challenge your audience faces and help them see it in a new way. Maybe why a common strategy isn't working, the mistakes people keep making, or the mindset shift needed to approach it differently. Readers recognise their own struggle and immediately feel understood. You become a trusted guide rather than an unreachable expert.

3. The identity or leadership book

This is less about tactics and more about who the reader needs to become. It speaks to moments of transition: stepping into leadership, claiming authority, letting go of an old identity. Many readers already know what to do. What they struggle with is the internal shift needed to do it with confidence.

4. The memoir or lived experience book

Your lived experience becomes the teaching, and you become the case study. It isn't a diary or a confessional. You decide what's relevant and what genuinely serves the reader. Your story isn't the point. The transformation is.

How do I choose the right book for right now? (Step by step)

1. Brain dump every idea. Get every book idea, theme and message out of your head and onto paper. Don't edit yourself yet.
2. Look for the common thread. What themes keep appearing? What message sits underneath all of them? Often your ideas are more connected than you think.
3. Check each idea against your top three business priorities. Which book would most help with more clients, speaking, programme sales or whatever matters most to you right now?
4. Check it against your ideal reader. Does it solve a real problem for the people you most want to work with? (More on that in who should I write my book for?)
5. Check it against the next step. Does this book naturally lead readers towards your offers, your community or a conversation with you?
6. Pick the type that feels most natural. Framework, problem-solving, identity or lived experience.
7. Write your concept in one sentence. "This book helps [who] to [achieve what] by [how]." For example: this book helps new managers to become confident leaders by giving them a practical framework for leading people in their first year.

If you can fill in that sentence clearly, you've probably found your book.

What did I choose for my own book?

There are already plenty of books about writing and self-publishing. Most of them focus only on the writing or only on the publishing.

My concept for AUTHORity was different: your book isn't just something you write, it's something you use. A well-written book is one of the most powerful assets you can create in your business, and it can position you as the obvious choice for the people you want to work with. Same topic as other books. Different concept. That's the difference I want you to find in yours.

What if I want to write all of my book ideas?

You probably will, eventually. Many of my authors go on to write more than one book once they've done the first.

But you don't need to write them all now. Your job isn't to choose the perfect book. It's to choose the right book for this stage of your business. That's where momentum starts. Park the other ideas somewhere safe and come back to them later.

Key takeaways

• Ask "Which book would best support the business I'm building right now?", not "Which book could I write?"
• A topic is what your book is about. A concept is your perspective on it, and what you become known for.
• The four strong types of business book are framework, problem-solving, identity or leadership, and lived experience.
• The right book solves a specific problem for a specific reader and leads naturally to working with you.
• Test your idea with one sentence: this book helps [who] to [what] by [how].
• You don't have to write every book now. Choose the one that creates the biggest opportunity today.

Frequently asked questions

How do I choose between several book ideas?

Measure each idea against your business. Ask which one best supports your top three priorities right now, which one solves a real problem for the readers you most want to attract, and which one leads most naturally to your offers. The idea that ticks all three is usually the right book for this stage. The others can wait for book two.

What type of book is best for a business owner?

There's no single best type. Framework books work brilliantly if you already have a method you use with clients. Problem-solving books suit experts who fix one specific challenge. Identity books suit coaches who help people through transitions, and lived experience books work when your story is the teaching. Choose the type that fits your expertise and your business goals.

What is a book concept?

A book concept is your specific perspective on a topic. It explains who the book is for, what problem it solves, what transformation it creates and why someone should read it. Leadership is a topic. Helping new managers become confident leaders in their first 12 months is a concept. A clear concept makes your book easier to write and easier to remember.

Should I write a memoir or a business book?

You can do both. A lived experience business book uses your story as the teaching, so your reader learns through what you went through and what you discovered. The key is that your story serves the reader. You choose what's relevant and what helps them move forward, rather than sharing everything that happened.

Can I write more than one book?

Absolutely, and many authors do once they've finished their first. Most entrepreneurs have several books inside them. The trick is not to try to write them all at once or squeeze them into one book. Choose the book that creates the biggest opportunity for your business today, finish it, and keep your other ideas safe for later.

Need a second pair of eyes on your idea?

Choosing your book is one of the biggest decisions you'll make in the whole process, and it's so much easier when someone can reflect your ideas back to you.
