If another person tells me not to use so many PowerPoint slides I'll go mad: I know! I'm not that happy with them either. It's just that when I sit down to prepare my material, I use PowerPoint and before I know where I am, I've got a set of slides...
I sympathise. But don't touch PowerPoint until you have prepared your presentation! Does that sound odd? PowerPoint is a resource you might use in your presentation-not the presentation itself. So: a suggestion, next time you need to present for say 45 minutes, grab an A4 sheet of paper. Divide it into say 9 boxes ( 1 per 5 minutes) and now create your storyboard. How will you end? How will you start? How will you grab their attention back in the middle? Think stories, exercises, questions and props. And then 1 or 2 slides. Give it a go: you'll love it!
The surgery will be open again later this week.
