When you sit through a how-to-do-a-presentation/public speeches training or watch a video or listen to a podcast, I bet they will tell you everything else but this one element that you really need to add to your presentations/public speeches.
If you work on adding this element in your presentation/public speeches you will realize that over time you will automatically not only please your audiences but will really in solid way add value to them.
This is one of the things that people will naturally like you for because there cannot be any other better investment of their time other than this when they are listening to you.
So, watch this video and I am sure you will learn something that you will appreciate. Plus, it is not very daunting task to do what I advise in this video.
