Speech Tip: Exaggerate? No.
An inspirational speech does not need to exaggerate. It only needs to emphasize. Help your audience know what they can do and how they can do it — and inspire them as you tell them why.
Overstating a success or a struggle is dishonest, and those listening will be fooled into believing something is possible that, in fact, is not. Instead of being disingenuous, simply tell your story.
