Common mistake
Writing a career summary instead of a business tool
The most common misstep is treating the book as a record of everything you have done. A summary of your career is hard to market and rarely speaks to a specific client. Big Impact Books makes the case on its blog for writing toward the work, clients, and opportunities you want over the next five to ten years.
A useful test: if a chapter does not help your chosen reader solve a problem you are paid to solve, move it to a talk or article instead.
