Reflect that your audience will not hurt you. If Beecher in Liverpool had spoken behind a wire screen he would have invited the audience to throw the over-ripe missiles with which they were loaded; but he was a man, confronted his hostile hearers fearlessly--and won them.
In facing your audience, pause a moment and look them over--a hundred chances to one they want you to succeed, for what man is so foolish as to spend his time, perhaps his money, in the hope that you will waste his investment by talking dully?
Concluding Hints
Do not make haste to begin--haste shows lack of control.
Do not apologize. It ought not to be necessary; and if it is, it will not help. Go straight ahead.
