I picked this book up in Waterstones one afternoon. It grabbed my attention because improving gravitas sounded pretty appealing, especially as i had to prepare for a best man speech and some work related public speaking. I'm not low on confidence by any means but i wanted to optimise the way i carry myself generally and public speaking has always been a weak point. I had some horrible moments at school and uni when i just completely choked. i tend to ramble, mumble and read from a sheet.
This book get's straight to the point, teaching you exercises to improve your confidence and gravitas immediately, gradually building up to a level where i personally felt confident to deliver the speech. Learning the psychology helped me with my nerves because it made me more aware of what was going wrong, why it was going wrong and how to rectify it. I like the quotes from famous public speakers and you soon begin to understand that gravitas is something that can learned, like those speakers themselves have been taught.
This book is very well written because i get bored easily and it kept me engaged. Every time i read a chapter i learned something new. Another thing i like about the book is that it's not just preparing you for a speech, it's arming you with the life skills to communicate with people more effectively and leave a lasting impression. I can honestly say, have changed my mindset and given me greater impetus. If you read one book this year, Gravitas would be my personal recommendation.
