Enthusiasm is a necessary qualification for effective speaking. When you show enthusiasm it is contagious. The enjoyment and knowledge that is demonstrated for your subject will result in increased listener enjoyment and your speech being more convincing.
For public speaking, the enthusiasm required, as described by Coleman Cox, "is inspired by reason, controlled by caution, sound in theory, and practical in application, reflects confidence, spreads good cheer, raises morale, inspires associates, arouses loyalty and laughs at adversity."
Enthusiasm in public speaking is about being passionate about the subject of your speech and being able to convey it to others. The enthusiasm must be demonstrated in your tome of voice, body language, gestures and facial expressions to transfer it to your audience. The feeling of excitement must come through as you deliver.
Some people are naturally enthusiastic and they are that way because they have developed the necessary habits. You must want to be enthusiastic to become enthusiastic.
Frank Bettger author of "How I Raised Myself from Failure to Success in Selling" attributes his success to enthusiasm. His advice is "act enthusiastically and you'll be enthusiastic." By acting on his own advice he put his "heart" into selling and went from failure to the top of his field for several years.
If you are not naturally enthusiastic, it can be created as a result of your attitude and enjoyment of the topic or by believing in a cause. By taking the time to apply the following it is possible to develop enthusiasm:
1. Choosing a positive optimistic nature and attitude
2. By putting your whole heart and soul into every you do
3. Do not let criticism put you off your stride
4. Develop a burning desire in your subject by thinking about it and living it everyday.
5. Have an active interest in people
6. Spend your time with people who are genuinely enthusiastic. Their positive emotions will "rub off" onto you.
Unless you want to be enthusiastic you will never be enthusiastic. If you are ashamed of the topic, or dislike it you will not be able to develop enthusiasm for it. Genuine enthusiasm only comes from something you believe in or enjoy.
One of the factors that contributed to the late John F. Kennedy's speaking success was the enthusiasm he displayed when delivering his speech. Sure, he had good speechwriters but without his enthusiasm the speeches would not have been nearly as effective. A person conveying their speech in a monotone voice, boring and steady manner will not be as effective at getting their message across.
An enthusiastic delivery can overcome other shortcomings in your presentation. Where you are not naturally enthusiastic it can be developed provide you choose to be. By being genuinely enthusiastic and combined with preparation and knowledge your public speaking will be more confident and effective.
