Have you been thinking about writing a book? It can be a fantastic marketing tool that sets you apart from the pack—and you can leverage it to get media attention for your area of expertise. In the past, you had to pitch ideas to publishers, of course, but today you can self-publish an ebook and release it on Amazon, Barnes & Noble and Smashwords. And, self-publishing a successful first book can be a great way to get the attention of a publisher for subsequent tomes.
