Initially, I thought the book was useless and filled with no techniques but just examples. But later on, It is good, I does tell you how to work deeply.
If you ask me, you should skip the chapter 2,3 and 4, and directly jump to the rule#1, I guarantee it would save your time.
For a review perspective, I would say the book is really useful but the first 4 chapters should exist in the way they do right now.
