One of my earliest posts on this blog was on “Tell them a story“. Every presentation is story telling. It does not matter how complicated your topic is, your success in presentation hinges on your story telling ability. In fact, all the great presenters and speakers have the ability to turn complicated and technical issues into SIMPLE story telling. Any fool can rattle off complicated equations and theories from a set of notes. Only the smart ones can explain them to a non-technical audience.
I think they call that communication.
