How to give good presentations

Most people -- and this includes college-educated folks -- do not know how to give an effective presentation. They tend to ramble, or they tend to focus on irrelevant details, or they use graphic ineffectively. Many of them also tend to read off of their PowerPoint slides, treating PowerPoint as though it were a teleprompter.

This generally indicates poor mental organization. It's one thing to use your PowerPoint slides to guide your presentation. It's yet another thing to read the content of the slides to the audience, treating them as though they were idiots. The same problem holds for those who ramble on and on, using a hundred words to explain something that should only require one sentence (and yes, I've seen my share of presentations like that).
