There’s nothing new in here that you’re not being bombarded regularly if you’re looking for ideas along similar lines.
The book promised 27 days, but if you follow the sequence of the chapters, you’re definitely going to overrun the timeline. The author cites several success stories throughout the book, but the information is so brief and generic that I doubt you will come away enlightened.
