From Page to Profit: The #1 Mistake Authors Make When Turning Their Book Into a Course (And How to Avoid It)

The Hidden Trap for Authors

You’ve written a book. You’ve poured months, even years, into crafting your ideas, your stories, your expertise. And now you’re wondering: Could this become an online course?

The short answer: yes. The real question: Will people pay for it?

Here’s the uncomfortable truth: most authors fall into the same trap when they try to turn their book into a course. They copy and paste chapters into lessons. The result? A glorified audiobook, not an online learning experience. And that’s where students lose interest, and authors lose sales.

Paula Rizzo (author of Listful Thinking, creator of the Listful Thinking Masterclass):

“Turning your book into an online course is one of the most powerful ways to connect with your readers.”

The #1 Mistake: Teaching Like You’re Writing

Books are designed to be read. Courses are designed to create transformation.

A chapter might leave a reader inspired, but a lesson should leave a learner changed, with a new skill, a solved problem, or a clear action step. If your course feels like a “read-along,” it won’t hold attention (and it won’t sell).

What You Should Do Instead: Think Like a Learner

Instead of asking, “How do I fit my chapters into modules?”, ask:

• What outcome should students walk away with?

• What action or reflection will cement this lesson?

• How do I break my content into digestible, progressive steps?

This shift, from telling to teaching, is where the magic (and the money) happens.

Step 1: Validate Before You Build

The fastest way to waste months of work is to build a whole course no one wants. Test demand with a low-stakes pilot:

• Run a live webinar on a key idea from your book.

• Offer a paid workshop for a small group.

• Collect pre-sales before recording the entire course.

If people show up and pay, you know you’re onto something.

Step 2: Add Value Beyond the Book

Free content is everywhere. So, why should someone pay for your course when they could buy your book or watch YouTube videos? The answer: structure, accountability, and transformation.

People pay for:

• Clarity - a step-by-step roadmap.

• Connection - interaction with you or a community.

• Change - practical exercises that turn knowledge into results.

Step 3: Build a Simple Pathway to Sales

You don’t need a flashy marketing machine to start. A lean system works best:

1. A free lead magnet (checklist, guide, or mini-lesson).

2. A nurture sequence that builds trust.

3. A clear invitation to your pilot course.

Barbara Oakley, professor and co-creator of the MOOC Learning How to Learn, based on her book A Mind For Numbers:

She co-created one of the most popular online courses in the world, with over 4 million students enrolled as of June 2025. Wikipedia

This isn't a word-for-word quote, but it's a powerful fact that speaks volumes: when done right, turning a book into a course can reach millions. Highlighting this can underscore the impact and scale authors can achieve.

Our Final Word

Your book is the script. Your course is the performance. One inspires, the other transforms. And if you avoid the trap of “chapter-to-lesson translation,” you’ll not only save yourself months of frustration, you’ll build something people are excited to buy.
