This book has very little to offer.
It says 'Confidence' but what about those Shy celebrities like Beyonce and Jeniffer Aniston who have an 'air' of shyness about them, which seems to BE their Charisma!
It says articulation, this one I will not disagree with, the way you speak is much more important than the words you use, for the most part...Then there's a lot of rubbish about how many big words you know and so and so forth....
Here's the TRUTH about what Charisma REALLY is...CHILD-LIKENESS.
Charismatic people are like 'grown up children', Their outlook is one of awe, excitement, passion, joy, desire to explore and discover, enjoyment of meeting new people...What does this sound like...A CHILD?
To be more Charismatic, just stop taking life so seriously, so ADULT-LIKE. Be a little more open, playful, cute and fun....Be full of hope, excitement, optimism...What you see in Barack Obama....Is everything you not wish to be..but what you USED to be.
PS: There's no real science or research to back up the claims, either.
