102: How to Know if You Have a Good Idea for a Book

Before you write a book, you need a good book idea. This sounds obvious, but deciding what you want to write about is a challenge.

You need to have an idea that excites you, is worth writing, and provides value for your readers. So how do you know if you have a book idea worth pursuing?

102: How to Know if You Have a Good Book Idea [Podcast]

After publishing four books, I’ve learned this is a tough question to answer. There are many factors that influence whether or not your idea is any good. But there are ways to remove the guesswork. The truth is you can know if people will read what you have to say before you even finish writing the manuscript.

This week on The Portfolio Life, Andy and I talk about how to decide if your book idea is worth pursuing and practical ways you can test your ideas to see if people are interested in what you have to say.

Listen in as we discuss how I discovered the idea for my next book. We also talk about how other authors decide what to write about and how you can get more confidence in your book idea before writing it.
