How to Be Charismatic

Master all three and you'll be charismatic. And to master all three, you will have to practice being present with people, and to be in the right mental state to project power and warmth.

Don't take my word for it. Because all this is from the book, The Charisma Myth, by Olivia Fox Cabane. She's a coach for executives wanting to raise their charisma. So if you want to build up your charisma, you should buy her book.
