If you are going to use a podium or lectern, set it to your side. There should be no physical barrier between you and your audience.
Mornings are best when presenting a convoluted topic. Afternoons are harder for comprehension and evenings are the worst.
You’re never just presenting to an audience. You’re presenting to who they’re presenting to.
If you’re in doubt, throw it out.
Emotion makes people act, logic makes people think. A good presentation has both.
