No, this is not a post about me (or anyone else) losing their edge, their sex appeal, or their money. It's about you, as an author, losing your inspiration, your motivation, your drive to complete your book project. As an author's coach, I see it all the time.
People start out writing their book with an abundance of excitement and drive. They've got an idea for a fantastic book and they're psyched about it. They've got the notes and the quotes; everything that'll make their book the best. But at some point, something happens. Oh, it could be the busy-ness of life, a family emergency, a business project that needs to take priority, or even just writer's block. Whatever it is, it causes the aspiring author to cease writing.
