Don't try to make too many points of apparently equal importance. If someone remembers, one year later, one thing you said, that's a highly successful presentation.

During my rather brief career as an educator I went to a lot of workshops...(haven't we all) probably the best one I ever saw was on the subject of public relations. The presenter used a lot of humour to reinforce a few main points. (This was more than ten years ago) Number one was: the most important test of any organization in the public eye, like a school board or something, is how they follow up a major blunder. A prompt, sincere apology and taking genuine corrective measures, will leave most people with a higher opinion of your organization than they started with.""

Now that was a successful presentation! I even remember a couple of other things he said, but that's a piece of wisdom that I've carried with me ever since.
