Power Points: Here's quick, but very useful tip… I always say don’t put text on a slide unless you’re going to give the audience time to read it. Very important. Either remain silent while they read, or preferably, read it out for them.
The worse thing you can do is to carry on talking, while they’re trying to read, then change the slide when they’re only half-way through. Then if you go through the slides too quickly, with insufficient time to absorb each one, the audience will get irritated and very soon (horror!) start to cough and shuffle. Oh dear.
