Writing a Nonfiction Book? Avoid These Rookie Mistakes and Publish With Confidence

Got a Story to Teach, Share, or Inspire? Let’s Turn It Into a Book

If you’re here, chances are you’ve lived through something worth sharing—or you have knowledge that could help others. That’s what nonfiction is all about.

Whether you want to write a self-help book, a how-to guide, a memoir, or something that blends them all, writing nonfiction isn’t just for professors or “experts.” You don’t need perfect grammar, a fancy degree, or a big following to start.

You just need to begin—and we’re here to make that feel a whole lot easier.

This guide will walk you through how to write, polish, and self-publish a nonfiction book that actually helps people (and maybe even earns you some extra income).

Step 1: Know Who You’re Writing For

Before you write a single page, ask: Who is this book for?

Are you writing for…

  • Busy parents who need quick advice?
  • Small business owners trying to grow?
  • People dealing with grief, change, or a big life moment?

Your readers don’t need a textbook. They need your voice, your experience, and your honest advice. Keep it simple, clear, and helpful.

Step 2: Make a Quick Outline (Don’t Overthink It)

Nonfiction books don’t have to follow a strict format—but they do need structure. Don’t worry about chapter names yet. Just jot down the big ideas or steps your book will cover.

Example:
If you’re writing a book about getting organized, your outline might look like:

  1. Why staying organized is hard
  2. Common mistakes
  3. Easy habits to try
  4. Tools that help
  5. A simple 7-day plan

You can brainstorm in Canva Whiteboards, a notebook, or even your phone. The goal is to get your ideas out so writing is easier.

 

Step 3: Write Like You Talk

You don’t need to “sound like an author.” Just be real. The best nonfiction books feel like a helpful conversation, not a lecture.

Tips to keep it easy:

  • Use short paragraphs and clear sentences
  • Don’t use big words if small ones work
  • Imagine talking to one person, not a crowd

Step 4: Edit Without Over-Editing
