I'm not sure why I bought this. It is good. I bought it after reading Stephen King's 'On Writing' - an excellent book, which frequently referred to this book. I think I thought that if I bought it I would be like Stephen King: an excellent writer. I think I bought 'in' to the idea of achieving perfection from this book. "This book will change my life" I thought. It didn't. I read it once and shelved it. It's really tiny too. Did I mention that? A7 size.
