Just finished a book called the Mystery Method, I noticed that this book isn't on the book list in the Wiki. Just curious on how many of you have read this book. Do many of you use these techniques? Have they worked for you?

I honestly enjoyed the book and I'm excited to start using some of the techniques, though I am a bit nervous and haven't truly ever gone into the field just to approach and apply the things I've learned. Any other "how to" style book recommendations or advice would be greatly appreciated.
