From Messy Ideas to Meaningful Books: The Role of Genre Conventions in Prescriptive Nonfiction

Last updated: December 10, 2025

When I was a kid, I loved playing with Legos. But I was a girl…with a sister…in the seventies…so we didn’t own any Legos.

The only time I got to play with them was when I got older and babysat little boys who had them. I loved it. We’d dump out the bin of Legos on the floor and build cool things all night.

I didn’t play with Legos again until I had my son. We got a fancy Lego kit followed elaborate instructions, and ended up with a spaceship.

But, my son never loved Legos like I had. He’d learned that there was a right way to play with Legos. You had to build the thing so it looked liked the picture on the box. It was hard and detailed, and not super fun.

The kit had sucked the creativity and fun out of playing. I tried to buy a box of Lego bricks that wasn’t a kit, but couldn’t find one. They didn’t exist (pre-internet).

Why couldn’t I find plain Legos? Because people love kits. 

As humans, we like knowing how to do something to achieve our goal. We want the step-by-step instructions to build the thing.

So what does that have to do with writing a book?

Nothing…and everything.

In order to write a book that works, authors must follow the rules of their genre. 

Readers expect this. But we get to be super creative when it comes to filling that content in with our stories, voice, and ideas.

This means that one of the first tasks you must tackle is to figure out the best way to put your ideas into a book. 

Will you write a self-help/prescriptive nonfiction book? Or, would a narrative memoir work best to convey your message?

Once you choose, you’ve got your instructions for moving forward, or your “Lego Kit.” Then, you can play with how your ideas will fit together to best resonate with your reader.

Prescriptive Nonfiction Genre Conventions

For prescriptive nonfiction, readers expect that you will:

• address a specific problem for a specific reader
• have a unique angle or approach to solving the problem
• take the reader step by step toward that solution
• encourage and inspire the reader to take steps to solve their problem through stories, examples, and anecdotes
• establish your own authority when it comes to addressing this problem
• Include research or anecdotal data to support your solution/framework

Knowing the expectations or features of your genre can create a creative container within which you can play. It’s like knowing you’re building a car or a spaceship. You have an idea of the end goal which allows you to move forward.

It’s the Lego equivalent of sorting your blocks into piles by color, shape, or size. 

If you’re feeling stuck or unsure on how to move forward with your ideas, start with genre. 

Think about your content and feel into which feels the most interesting and exciting for you to write. Which genre would your content best “fit”?

If you need help with this but aren’t sure about a full-book coaching package, you can schedule a “Book Chat” to discuss it and work through your ideas.

All my best,
