These days many book proposals include a mission statement after the About the Author section. Here you answer the question: “Why do I feel compelled to write this book?”
Or answer these questions:
- “What’s my purpose in writing this book?”
- “What’s my mission in writing this book (or how does writing this book fit into my mission in life)?”
- “What do I want to accomplish by writing this book?”
The answers to these questions constitute much of what goes into your mission statement, which consists of one paragraph (at most two—but no more than about half a page) written in the first person tense that explains why you must write your book.
