I bought this book after seeing and hearing Dr David Hamilton a few weeks ago. I was blown away by what he said, by his dynamic presence and his total integrity. I'd been a bit cynical beforehand, thought it would be another "new age-y" thing, but I was so wrong! All his arguments/statements are based soundly on scientific research findings, nothing is pure theory, and it's incredibly powerful - the power of the mind is demonstrated over and over again, and it's really uplifting. Buy it! Read it! Remember it! Then go do it!
