Every book has a cover. That’s easy, right? But your book, the one you get mad at writing, should have a great cover! But even the greatest artist of all time cannot understand what the Hell you want if you’re not able to deliver the right message. It’s a different way to sell your work, isn’t it? What you have to do is sell the basic idea of your book to another person, the artist, to help him/her to maximize his/her efforts. Is it easy? It should be, because you’re a goddamn author / publisher and that’s a part of your work.
