If you’re staring at your page or your paperwork the entire time, you’re going to lose your audience very quickly. Make sure you know your presentation inside and out. Remember, amateurs practice until they get it right; professionals practice until they can’t get it wrong. If you’re nervous about the presentation, this is all the more reason to practice, practice, practice and tell you know it inside and out. If you can walk around the room and still talk about your presentation, engage your audience and get them passionate about the idea, then you’ve got it.
