Nothing centers your focus on things you’ve learned in your career like writing a book about them.
Unless you launch into some stream-of-consciousness, rambling mumbo jumbo, it forces you to categorize your knowledge into specific chapters that make sense.
But within each chapter, it’s easy to succumb to the notion that future readers will hang on your every word, even if it’s Gone With the Wind, Volume II. They won’t.
So you have to be succinct enough to get to the actual heart of the matter, even if there seems to be many hearts of many matters. I had to follow my own advice: Be decisive—pick something and run with it! (Thank you, page 49).
I learned these things (and others) while writing my book, The High-Growth Nonprofit.
