I've self-published a handful of books, one which became a WSJ best-seller and written two with a traditional publisher.

Working with a skilled editor who teaches you how to structure a book and support your arguments with evidence is one of the most significant benefits of working with a traditional publisher. The real value isn't getting a book contract; it's learning how to see a complex and somewhat vague project to completion.

My self-published book was nowhere near as well written as my two traditionally published books, but neither sold as well for one reason: emotional resonance.

The self-published book was just a series of Facebook status updates. But people's reactions allowed me to see how the material was resonating.

This is what makes Elle's approach brilliant. With each chapter she shares with her readers, she's getting an opportunity to get feedback from people whose opinions matter's most: her readers.

She's inviting them to be part of the journey and building a relationship with them. The book is theirs as much as it is hers. There's an endowment effect at work. People have the sense that "I helped make this, so of course, I want to own it when it's done." They almost value the book more because they've invested THEIR blood, sweat, and tears along with hers.

Elle, you've shared an invaluable lesson for anyone who wants to write a book. Every aspiring author who wants a book deal needs to read this article.
