You're the messenger, not PowerPoint

One of the keys to being an outstanding presenter is knowing your content thoroughly. This requires rehearsing. When you can give your presentation without the aid of presentation software such as PowerPoint, it is only then that these tools can help to support your message. When standing to present, you’re the messenger, not PowerPoint. Try presenting without PowerPoint. It can be a liberating experience. You can create wonderful images by using expressive words, intonation, and facial expressions.
