Some very interesting facts, some great insights, but, over all, too much of the book was like, "I do what? What does that mean?" I couldn't decide if the techniques were too generalized, if I was over-thinking them, or if they were too specific to be used for general purposes even though they were supposed to be good for everything.
I really expected to like this book better because of the subject matter and all of the sources where I had heard it mentioned or recommended but I found it somewhat annoying--though I can't really say why.
Hearth Math Solution is a powerful book which will provide insight or an alternative to ones everyday thinking process. Strong enough in my opinion to change what we have been taught to believe and how to view our world.
