I was going back and forth with a client today about what words should go on a slide. She was arguing for one sentence and I was arguing for another. And she said to me, "Oh, you're thinking about the audience. I was thinking about me."

We both chuckled. But her realization was also a realization for me. 

I'm always putting myself in the seat of an audience member and I assume others are doing that, too. But I think it's tempting when you are the presenter to think first about what you need on the slide to remember what you're going to say. I call this using slides as crutches. You can do that, but it's at the cost of giving your audience the experience they deserve.
