I seem to have a different view than the other reviewer. The book got off to a bad start when, on page 4 (page 3 is the first text page) the authors attributed to Newton a philosophical question the Bishop Berkeley actually propounded. This was followed by a couple of other science distortions before we got onto the NLP part of the book. I found the review of NLP to be cursory and incomplete. Nor were any new insights brought to light. Perhaps as much as 40% of the book (all 230 pages of it) was real or imaginary client interviews, which means a lot of white space.Save your time and your money. Even Anthony Robbins has a better exposition on NLP (although it is buried in a lot of "feel good" text)
