The advice given isn't nearly as meaningful as I hoped. It truly deals with only one scenario and that is you giving a speech to an auditorium or a boardroom full of people. It doesn't deal with the vast amount of interactions it promises, including job interviews and deal-closing pitches, which it splashes across its cover. If you need help with a TED Talks type of presentation, then you might value this book. Otherwise, it's a bit of a disappointment. I don't recommend it.
