It is important to have your main, broad concept clear in mind before writing your speech. Do a broad type of research that allows you to see the topic from all sides. Then, write down the key points you want to touch on during your speech. A thorough presentation can pay off when you've got the audience asking questions.

Try to relax before and during your speech. Breathe deeply and remember that you are well-prepared, so you have nothing to worry about. Some say that it helps to envision your audience members in their underwear to help you relax. This sort of visualization can help you look and feel more relaxed while speaking.
