The first thing I want to say is this: I feel your pain. You have a wonderful idea for a book. You start working on it. You get stuck, and you keep going – because you’re persistent, and you know that if you don’t keep at it, you won’t finish your project. Then you set it aside for a bit before returning to it with a view to making it as good as it can be – polishing it up to the very best of your ability.
