I would take this book and concept with a grain or two of salt, because not everything it espouses is for everyone, and I found not all of it completely rang true with me. That said, the very first book in the series by Julia Cameron has something to offer just about anyone who is looking to cultivate their creativity, not just in writing per se, but using writing as largely the outlet and mode of expression. Even if you only take one practice or exercise away from it (the daily writing routine is a good one, and one I’ve personally kept up for close to 12 years now), it’s worth it.
