seaptho, cast your mind back. Glide backwards through your memories until you find a clear memory of the last time you had to sit through a presentation with a large group of people. Hold that memory. Let it take shape. Think about yourself, what the audience was like, the atmosphere, the mood.
Then ask yourself: “How much attention do I pay to other people standing up on stage yammering?”
That’s how much attention these other people will be paying to you. Probably less. The reason you have PowerPoint slides is so that when they tune back in every once in a while, they’ll have something short to write down.
It’s pretty much just like giving your speech in front of the mirror, except when you’re on stage you’ll probably also get to play with a laser pointer.
Failing that, many people who don’t speak in front of large groups very often find it comforting to get to the moment of truth and discover that they cannot see a god-blessit thing, other than themselves. If you’re speaking for 500 people and you have slides, that means you also have a screen and a projector of some sort, and in order to make that properly visible, everything else needs to be pretty dark. It makes you effectively night-blind, mercifully unable to make out anything of any note out in the house. Unless you’re so terrible that they rise up and start pelting you with rotten fruit, you have no way of knowing the audience is even out there.
