For some reason we all seem to feel a sense of being under scrutiny when we speak in front of people, that they’re just waiting for us to “mess up” so that they can fall about laughing at us. If you were an audience member, is this the way you would approach a presentation? Probably not. Then why do we as presenters usually feel this way? The truth is this:
You audience wants you to succeed.
Try and remember it, and give yourself a break. Get up there, put a smile on your face and give your best. You may be surprised at how well it all works out!
