The Real Problem

You have the expertise to write a book that changes everything.
You just don't have a system that tells you exactly what to do every day.

Most people who want to write a book spend months — or years — stuck. Not because they lack knowledge or their idea isn't good enough.

They're stuck because there's no clear daily system. No one is telling them exactly what to write, in what order, and how to make the book attract clients once it's done.

When you have the right system, a client-attracting book doesn't take years. It takes 30 days.

None of these are talent problems. They are system problems. And a system is exactly what this is.

Who This Is For

This works for nearly any non-fiction business.

If you have expertise to share, a book is your most powerful client-attracting asset.

Meet Your Guide

Hey. I'm Joshua Sprague.
I've helped 13,500+ people write client-attracting books.

When I wrote my first book, I hemmed and hawed for 9 months. I'd written a total of maybe 5 pages.

Then a mentor — someone who had written multiple NYT bestsellers — laid out exactly what I needed to do and gave me a good kick to get it done.

What happened next blew my mind.

I wrote my first book in 21 days while working a full-time job. That book went on to become a #1 Amazon bestseller.

I realized I was onto something. So I started teaching others. 13,500+ authors later, the system is proven and the results speak for themselves.

Now it's your turn.

Questions

Before you go.

Does this work if I have no time?

Yes. The daily assignments are designed to fit into a busy schedule. You don't need full days — just the consistency to open the email and do the work.

What if I don't know how to structure my book?

That's exactly what this solves. The proven outline method takes the guesswork completely out of structure — you'll know exactly what goes where and why.

What if I have too many ideas and can't focus?

The Big Book Idea Formula was built for this. It helps you find the one idea your book should be built around — and filters everything else out.

Will this work for my industry?

The system is built for non-fiction, which means it applies to virtually any business where you're selling expertise — coaching, consulting, services, courses, and more.

What happens after I join?

After you complete your purchase, you'll receive a confirmation email. The challenge always begins on a Monday — so your daily emails will kick off on the closest Monday following your purchase.

No more waiting. No more overthinking.
In 30 days, you can have your book.
