Know your audience. Before you write your next speech, wedding toast or presentation at work. Research and know your audience. That information will garner great benefits. For example, if you knew that you have an "just give me the facts," audience, you can tailor your speech or presentation with that in mind. You could highlight statistics, backed up with power point slides that are to the point. No more that three bullet points on each page will do the trick. You will lose your audience if the slides are cluttered with a bunch of words in small fonts.
When writing your speech, break it down into three sections. A. The Introduction,
B. The Body and C. The Closer. The introduction is a great way to break the ice and inform your audience of what's to come. The body will include the major points you outlined in your introduction. The closer will serve as a summary and to end your speech on a high note.
