We are often asked to make a speech in life. Most of us are afraid of it and don’t do a good job. Here are some simple steps to make your speech a successful one. First of all, find out everything you can about your subject and at the same time find out as much as you can about your audience. Who are they? What do they know about your subject? Put yourself in their shoes as you prepare your speech. Then try to arrange your material so that your speech is clear and easy to follow. Use as many examples as possible. Never forget your audience. Don’t talk over their heads or talk down to them. When you are giving your speech, speak slowly and clearly, look at your audience and pause for a few seconds from time to time to give your audience chances to think over what you’ve said. Just remember: be prepared, know your subject and your audience, say what you have to say and be yourself so that your ideas will bring you and your audience together.
