1. If you want to appear to be good at ad libbing, spend lots of time talking to yourself in the bathroom mirror and put in time on your computer constructing notes, outlines, bullet points, and sample questions and answers.
2. At least a week before you give your speech, you need to put your ideas and message formulation to bed.
Even if you only have a few hours before the speech is to be delivered, spend time rehearsing. And that means standing up and saying the words out loud. Not just in your head!
3. Mark up your script with underlines and pauses and listen carefully to how the speech sounds after each rehearsal.
Be very critical of your own speech patterns. If any word or phrase sounds awkward, re-work it or get rid of it completely.
4. Time your rehearsals and make sure you use only the time allocated. You’ll find with each rehearsal you get smoother and remember less is always more!
