Yes, at home. If you get caught trying this in the work loo, your colleagues will recommend a psychiatrist.
This is for you if you suffer from symptoms of nervousness that are obvious to your audience. Examples: a nervous smile, a tremor in your voice, speaking too fast and without pauses, a twitch, or very little body language, a reluctance to look directly into people's eyes. If any of your symptoms are like those, then this cure might work for you.
The method works for two reasons. First, you're showing your own brain the difference in symptoms between nervousness and confidence. Second, by practising the symptoms of confidence, you're building into your brain the circuitry of confidence.
Keep building and the act turns into reality. Make confidence a habit.
Of course it's not about the blank screen itself, but what you're doing at the time.
First, you need to know how utterly simple it is to go to blank screen. EITHER... on the clicker, press the blank screen button (most presenters don't know it's there). OR... on the keyboard, press the 'B' button. Either way, just press the same button again to return your slide to the screen. The button-pushing is not a problem.
Now, picture this:
Audiences want that. They want you in charge and they want you directly tuned into them.
So why aren't all presenters doing it already?
Because it takes courage - especially when you've been used to using PowerPoint as a crutch. When we face our audience directly, we feel vulnerable. That's why so many presenters step to one side, turning themselves into voice-only robots, us into comatose zombies, and the message into dust.
How to get a dose of that courage? See the rest of my blogs on this website.
Wait! You think your entire presentation has to be on the screen? That's rarely true, not even in full-on conferences. Please take another look at all your slides and ask yourself, Which way will this content have more impact? By adding my voice to what is on the screen? Or by delivering it while looking the audience in the eye? Be especially ruthless with word-only slides, which have near zero impact.
For now, if you like that picture of yourself in 1. and 2. above, here's a final tip. Get hold of a projector in advance and practise the movements. Better still, get a friend to watch and give you feedback. Get your body and brain used to it. Then, for the real thing, look forward to audiences impressed by your increased personal authority.
Try it. Then consider this - there's an even better way to use the blank screen to your advantage. Go to PowerPoint Tip 10: Insert a 'sleep slide'
