Something all writers should do is look to the masters for inspiration and guidance, especially when they are as I am, trying to grow as a writer, so I've recently ordered these books to help me out.
I wasn't sure if I was up for it because this isn't the type of book you can scan for information, but then I read his opinion on vocabulary. Lately, I've been fretting, or panicking rather, about my vocabulary so this peaked my interest. His advice was to not worry about it, to let your vocab be true to your voice, whether that's simple or not and he gave examples of how successful authors have done that.
His advice took the stress off and demonstrated that this book will be realistic. I can't tell you how many books I've read that say you have to do this or that or you'll never be a good writer, but I've learned the all-or-nothing attitude doesn't sync with the artistic and ever-changing nature of writing. So I'm going to keep reading.
