Your book! Your business card!
One great way to add credibility to you as a speaker is writing a book. Instead of being a speaker, you are now an author who happens to speak on your expertise. Even being a business person, a book gives you the label as an expert.
You do not have to write a book the size of Leo Tolstoy’s War and Peace. All of us have enough knowledge in our business lives, that a simple pocket book would be sufficient. As they say, “It is not the size that matters, but the content!”
Start by spending 15 minutes each day or 2 hours a week to write a series of 150-200 word essays. In a year’s time you have the makings of a book. Look for someone who can edit your writings, followed by graphic designer for the cover. Then decide if you want to self-publish. Voila, you have a book!
