I have to admit that I am very disappointed. It is ironic that a book so relentlessly advocates essentialism is so non-essential: repeat the same materials emphasizing the importance of essentialism in different ways over and over again. The importance is justified without the need of any emphasis, otherwise I would not read this book. My problem, which I believe might also be the problem for a lot of others, is how to differentiate the essential from the non-essential. To this point, it looks like the author has failed to provide any meaningful suggestion, let alone insightful framework or process or logic flow. If I recall correctly, the only suggestion I see is to increase the threshold of your decision. If the candidate is not 90%, then don't make decision. What a waste of time.
