I'll keep this simple and to the point – just like the book does! I am just now finishing this and have enjoyed every chapter. There is NO fluff in this book. You don't have to sort through chapters and chapters of boring, basic information. He gets right to the point in each chapter and makes it very easy to understand what you're doing and why. I learned something from every chapter.
