You've already got what it takes, or why public speaking experts should shut up and sit down.
You already have everything you need to be an effective, charismatic speaker. You do. You don’t need to adopt certain tricks or mannerisms. Nor do you need to speak with an artificially amped-up enthusiasm or energized voice. You do not need to move in this way or that. Or use props or PowerPoint. All of these suggestions, though well-meaning, keep us struck in the illusion that we need to be other than who we are right now, in this moment, in order to speak well in public.
