How do you recover from a memory lapse when giving a presentation? My advice, don't tell anyone your audience can't see your outline. They don't know that you've forgotten anything unless you tell them. They're not mind reader's. So if you forget your third point, you just finished your second one, but you remember the fourth and the fifth, go to the fourth or fifth. You can always come back to the third point.

You can glance at your notes if you're not close to your notes at that moment. Wait a second pause, look thoughtful. Walk a few steps glance at your notes. It's okay to forget. But what you don't need to do is say oh my god, I forgot what I'm going to say, Oh, this is embarrassing. Where am I?

People are not going to notice that you forgot something. They'll notice your reaction. So the secret Just don't tell anyone.
