Over the years I have often been asked the equivalent of "What’s your
secret for public speaking?" And I have been badgered to hold seminars or
workshops in public speaking and sermons. The truth is that a short
series in public speaking wouldn’t help much. The secret, if there is one,
to effective public speaking is: (a) Doing a lot of it and, (b) getting a
critique from someone who knows what he is talking about.
But I'll admit that there is more to it than experience and correction.
There are many principles and techniques that make a difference–sometimes a
big difference–in the effectiveness of a public speaker. See the links at
left for some ideas.
