I am honestly not entirely sure what to say about this book. The message is stop working harder, start working smarter. As a USA Today bestselling author with multiple number 1's under my belt, I wasn't completely sure how the advice in this book would apply to me, but actually, I came up with several ways to implement this without quitting writing (to move into sales) or hiring a ghostwriter. I was uncertain how to take my personal development to the next level before I bought this book. I'm now working more efficiently. I spent the last 2 months on a mini-retirement traveling the world with my husband, and my book sales are up on new titles. I am spending FAR less time on the little things and overall I feel like I have a positive plan going forward, which is exactly what I needed. If I ever meet Tim Ferriss in person I'd like to thank him.
