Great post! I think you highlight some pretty important points when it comes to public speaking. The first one being Practice. Like the old adage says "practice makes perfect". The more you repeat something, the more you gain experience with it, and the more you become comfortable with it. This will allow you to react better to your audience. Also know the details of your presentation.... When are you presenting? ..... Who are you presenting to? ..... How long are you presenting for? ..... What are you presenting? All of these questions have a direct impact on how you form your presentation. Knowing your audience goes a long way to crafting a successful public speaking presentation!

I have been involved in both stage acting, and public speaking. The second has always been the more intimidating of the two!
