Fellow speaker,
World Champion Speaker Darren LaCroix suggests reading a letter at the beginning of your speech to capture your audience's interest. The letter should directly relate to your presentations subject. For example, if you are selling something, the letter could be from a very satisfied customer, detailing the reasons they like your product so much.
Lettered,
Tim Wilson
