I can`t give a first hand account of this read, as I purchased it for my son-in-law. However, I can report that he felt the time spent reading the book was worthwhile and that he gained one very good suggestion, one that he was going to integrate into his presentations, confident it will make a difference. His comment to me was that ìt`s such an obvious`one, he couldn`t believe that he didn`t think of it himself!! For my part, at least one good idea that makes a difference, was all I had hoped for.
