Your Book Brief is the foundation of everything. Fill this out before you write a single chapter. It forces you to clarify who this book is for, what it's about, and why it matters. You'll come back to this page whenever you feel lost or stuck.
(What are you calling this book for now? It doesn't need to be final.)
(If someone asked "what's your book about?" at a coffee shop, what would you say? Keep it to one sentence.)
(Describe your ideal reader. Be specific. Not "everyone interested in productivity" but "freelancers in their 30s who feel overwhelmed managing their own schedule for the first time.")
(What gap does it fill? What's missing from what's already out there? Why are you the person to write it?)
(After reading your book, what should the reader know, believe, or be able to do that they couldn't before?)
(How many chapters are you aiming for? A rough word count target? For reference, most nonfiction books are 30,000 to 60,000 words, which is roughly 10 to 20 chapters of 2,000 to 4,000 words each.)
