I’m a TED fanatic. Ideas worth spreading. The short presentations are on such a myriad of subjects that anyone can find their interest. Or they can find a new interest.
In order to give a short presentation the presenter must have culled well. What is left gets to the point quickly and clearly.
When someone sends me an hour long video, a rambling interview, or a lengthy seminar I want to scream at them, “give me the summary, what are your main points?” Use a mind map and get your topic down to its essence, it’s key words, it’s key phrases, what you most want others to take away.
