Jeff Davidson, MBA, the author of The Complete Guide to Public Speaking, is a work/life balance expert. This is a great example of a persuasion speech — it would be hard to disagree with him by the time he is finished. This 2,879-word talk takes at least 35 minutes to present, he says. That is a rather slow pace because this is filled with information that needs to be digested slowly and each argument builds carefully on the last one. The speech, "Time Flies Whether You Want It to or Not," is particularly notable because of its use of many questions and startling statistics. But Davidson also relies on lists, tips, and quotations to reinforce his points.
