What makes people want to see TED talks? Usually because speakers that go there have great ideas to share. And what makes them so interesting that people can be engaged for such a long time?

I would personally love to acquire such incredible gravitas. They always look so collected, and yet so confident. These people are truly inspiring, and I'm telling you there's a way to get there.

How do you become more confident and interesting when speaking in front of others, and how do you add that special something that makes people want to listen to what you have to say?
