Query: Turbocharge? Depends on your interpretation of the word.

As a marketing communications practitioner, I too was impressed with Vitale's web site, and agree that some of his online tips are quite useful and insightful. However, Vitale's "instant writing method," described in Turbocharge Your Writing, isn't really insightful or new. This book tells you what to do to get started on your writing project. If you already know that you need to organize your thoughts pre-writing, and that you need to write and re-write, and that you need to step away from, and then return to your work with a fresh view, then you don't need this. If you're hoping to find suggestions for enlivening or punching up your writing, I'd try one of Vitale's other books. However, if you're completely (and I mean, completely) new to the writing practice, maybe this will help you get started.
