Speaking has been described asenthusiastic conversation, projected at a higher level of energy, to more people, and over a greater distance. Some years ago, I spoke to 3,000 people at a new hotel in Orlando. My talk was a major part of a four-day conference.

For ninety minutes, I threw my voice to the back row of the room. Afterward, I was exhausted.

Copies of the presentation were reproduced and distributed to thousands of people.
