I read this book in one sitting, and am going to return to it again and again. The style of writing is not only easy to read, but more importantly, the messages are simple yet profound. It is not often that I have read a book that from the first few pages gave me an insight into something that I had almost taken for granted. The concept of productivity is both easy and complex and Mr. Jennings has done what few authors are able to do and that is make the complex simple. Every owner of a business has to read this book. It is not filled with platitudes that sound good, it is filled with ideas and insights that can change a business and a life. I highly recommend it.
