Bests & Worsts Reviews from Amazon

I have heard Jim on several podcasts and was very interested to hear a more thorough explanation of his methodologies in his book. Unfortunately, that is not what his book is. What I do now know is that apparently his website and online courses are where these detailed explanations lie. I guess it is my fault really. He makes some very impressive claims on the benefits his methodologies provide. I was seemingly foolish to expect he would offer those kind of secrets up in a twenty dollar book. Obviously the only way to get something like that is through his $500 plus courses. I apologize for my naivety. This is mostly a sales pitch for his online courses with a few unoriginal tips pilfered from long-standing thinking on brain health and function.
