Creating your presentation in PowerPoint before you have your key points and logical flow worked out on paper is like a movie director hiring actors and starting to film before there is a script in hand.
A common problem in presentation graphics are designs which have
too many elements or lack a clear focal point.
The best presenters illustrate their points with the use of stories, most often personal ones.
“The worst presentations or speeches are the usual ones , the ones that are perfunctory , routine , safe , and utterly forgettable .”
The more you know your material the less nervous you will be. We fear what we don’t know.
