Most speakers I know write their books too early, long before they’ve honed their message and established their uniqueness. That’s why the average speaker sells less than 250 copies of their book, and rarely write more than one. Most speakers books are Think and Grow Rich regurgitated. Invest the time in creating your unique point of view and put it in your book. Take a stand and write in strong, direct language. Writing about positive thinking is great, but it’s been done over and over for the last 100 years.
