Prepare - Good speech or presentation didn't happen by accident. Preparation is the key. Not only we need to prepare our content, we should also get to know our audience, venue and the equipments well.
Practice - Rehearse as many time as you can before presenting. The more you rehearse, the more confident you will be. Rehearse infront of a mirror to check your body movement, hand gestures and facial expression.
Present - Don't chicken out! Present your speech and find out which are the areas to improve instead of finding excuses not to present.
