If I haven't given you enough reasons to rehearse and rehearse in the room where you're giving the presentation, you've got to figure out where is the projector aimed in relation to where you're standing. Because you can practice your own PowerPoint on your laptop, or you're just sitting down looking at on your screen, there's no distractions. But then you go to some convention conference, even your own conference room, you stand up and all of a sudden, you're blinded by the light. And your body is casting shadows on the screen. So it's confusing and it looks like you're putting on some sort of a puppet show with your hands. So you need to be keenly aware of where everything is.

Now. If it's your own event, you can try to get there early and figure out possibly change things so there aren't distractions. You want to be able to walk around the room. Now you heard me reference how You can hit the letter B for black or have a black slide and when the black slide is up, you can walk in front of the projector, no one will notice. But if you just have white, or if you have whatever screen you were showing, and you're now walking in front of the projector, it's gonna look horrible, it's going to look distracting. So you need to be keenly aware of where every piece of the room is, that's a part of your presentation.

And you need to rehearse and you need to know exactly how you're coming across. And that's one of those things where you need to have either a video recorder which you should, frankly, never rehearse without. And it can just be yourself or another colleague there in the room who can be looking at because you might not notice that you're creating shadows on the screen. So that's why it's always better to practice not just on video, but with another partner who can give you feedback on anything that could be distracting
