This audiobook is three books in one: Write Better Faster, The 8-Minute Writing Habit, and Dictate Your Work. What they don’t tell you up front is that these books are presented out of order. The first book in the series, Write Better Faster, is pushed to the end. Not really that big of a deal, save that the author mentions it here and there as a previous work in the series, which is more cross-marketing for her sake than actual help for you, unless you bought the books separately.
I’m no stranger to books about writing skills, and I can tell this is going to be a useful series. There are plenty of tips and tricks in here that can be implemented with little or no effort. It ultimately does come down to implementation. The more you use the tools in the box, the more useful the tools become.
