Think of it like talking to your friend in a casual awesome conversation. Think of it as something fun. Not only is it one of your greatest assets through life but it helps you be superhero status comfortable in your own skin.
After years of speaking to groups of all sizes, I still do not think I have it down completely. I had to really think hard, therefore, when a friend asked me recently how I gave such good talks and if I would mind sharing my "secrets."
