First, I've never used PowerPoint, because I've never used Windows any more than absolutely necessary, but I've used similar tools.
Second, when preparing for a presentation, I make sure that someone could get the gist of my talk from the materials, even if they were not there to hear it. That means I write very succinct statements on each slide, not vague one-word "bullets".
Third, I never read from my slides. I assume that you can read them, yourself. Instead, I paraphrase a point, and then add value by offering insights, providing examples and analogies, and exploring implications of the ideas presented.
All of that is "wrong", according to some self-proclaimed experts. Fine. My presentations are not boring and I became a DMTS with my approach.
