Make mistakes intentionally
This is another trick I encourage you to try. Once I “accidentally” dropped my notes on the floor, and while picking them up, I warned the audiences that the presentation will be more confusing after this. I heard some laughter from the floor.
The idea is to gain control of your audience. If you can make them laugh and be more interactive with you, your presentation will have that casual feel to it which will make it more memorable than others. Ultimately you will find it easier to do.
