Nothing has been proven more powerful than the written word. (And if you want to make an argument that film/video and/or the spoken word is equally powerful--I submit that they all started with being put to paper and in writing first.)
How can you transform lives? What lessons have you learned that you would like to impart to others? What do you wish you had known long, long ago? If you think about it long and hard, you may realize that you have a lot to share with your audience. If that’s the case, a book gives you the opportunity not only to transform lives around you--but also to transform your own.
