Not long ago I worked with an energetic, creative group who, while focusing on presentation skills, wondered how to best engage their audiences. I asked them what engagement strategies they appreciated when they were in the audience. They had plenty of ideas about engagement techniques that I think any speaker could benefit from.
There are as many excuses for giving bad presentations as there are stars in the sky. "I didn't have time to prepare." "I was hungover when I gave it." "My boss made me give the presentation." "I was nervous." "I lack confidence." "My dog was sick." Nobody cares about those excuses.
