Many presentations fall apart not because the ideas are weak, but because the slides are doing too much at once. When a single slide contains multiple messages, charts, or competing points, the audience stops listening and starts decoding.

In this episode, I explain why the "one idea per slide" principle is so effective—and why it's one of the fastest ways to improve clarity in presentations. You'll learn what "one idea" actually means, how strong sentence-based titles do most of the work, and how to use visuals that reinforce your message rather than compete with it. The episode also covers where detailed analysis belongs (the appendix) and how to use the three-second Glance Test to ensure your slides support your voice, not replace it.

If you want your slide decks to feel calmer, clearer, and more persuasive, this episode offers a simple rule that makes a big difference.
