Each government employee should spend a few minutes with Ted Talks---Ideas Worth Spreading. http://www.ted.com/
Find some subjects of interest and watch to see what develops in YOU. The presentations are, by definition, concise. Rarely does any speaker
go over the 15 minute suggested time. That time element is part of what makes Ted Talks such a great tool. If you can't give your "elevator speech", then go back to the drawing board until you can.
Watch at least three (3) to get a feel for how they are constructed. You will learn that sprightly presentations work. Using humor, personal examples get the listener's attention. You will soon learn, that if we were all thinking like this, we would get alot more done, in our families, in the workplace, in our nation, which is part of our ever expanding World.
You can listen on your home computer or through your home download of iTunes.
