Meet people (even if you know them) as they come into the room, shake hands, have a brief chat with them to help show your confidence and ‘break the ice’.
Show enthusiasm for the subject. If you don’t, your audience won’t be enthusiastic either. Put a lot of energy in and that energy will transfer to the audience. It’s called charisma.
Stay out of the way of your visuals and use the space that you have to move around.
It’s OK to move toward the screen and touch it to emphasize a point and it’s great to address individuals by name to build a sense of connection with the people in the room.
Keep your body “open” to the audience as much as you can and that helps you keep eye contact too. An occasional glance at the screen should be all you need to see to speak about the slide’s
80% of your speech should be said straight to the audience so get into the habit of looking at the audience as you speak, and saying nothing as you look to your materials for your next ‘cue’.
Don’t ever read your slides word for word to the audience. Your slides should be a simple collection of key words and phrases that are there for their benefit.
Use slide and PowerPoint ‘builds’ like they do on the TV news, for emphasis and impact to help you make your points powerfully.
Personalize your presentation. Use your life experience and humanity to sprinkle stories, thoughts, and personal views throughout your talk.
Real confidence in a presenter is about talking in good faith to your audience, you don’t have to try to be anything other than yourself, speaking with skill to get your message across.
