When you finish your eBook or print books, you have a product you can sell. After you finish the book be sure to write the all important sales letter. The sales letter is the key to sales flooding in. Each book will market another book. Books help promote your service as well. Like a messy room full of clutter, you just want to close the door on your project. If you really don't want it now, then make it ok not to do it. Or, if you are blocked in some way discover what that means and keep taking.
