To be a self-published author is far more than just being an author. Learning and applying the skills of promotion of your books are essential to stand any chance of earning from your efforts. Janice discusses how she self-promotes.
Whether you are an Indie Author, Publisher or Illustrator you must promote your book or at least hire someone to do it for you. I spend hours every day doing online promoting to all sites, e.g., FB, TW, LI, Pinterest, Goodreads, iAuthor, Google +, etc. There are so many sites out there today that you have a veritable smorgasbord of choices and the world is at your fingertips.
