第三条准则是少用幻灯片。我做演讲时通常不用幻灯片。幻灯片在图表展示或视觉辅助方面十分好用，可以对重点起到补充作用。但很多人使幻灯片成了演讲的中心，而非演讲者本人和传递的信息。大多数听众在看到过多幻灯片或者信息量过多时，脑子会变得麻木。
How can you make PowerPoint effective? Be simple. Use short words and phrases to make large conceptual points, and never go longer than 10 slides. Get the audience to focus on you and your words, not the slides. Giving a speech is pointless if no one is paying attention. You need to grab your audience from the beginning by asking questions, telling stories and relying on your own speaking rather than a bunch of boring slides. If you can do those three things, then your battle is already half-won.
如何使幻灯片产生效果呢？一定要简单。用简洁的词汇和短语来阐述大的概念，而幻灯片的数量不要超过10张。让听众关注你和你的话语，而非幻灯片。如果没人听，演讲就失去了意义。你一开始就要通过提问来抓住听众的注意力，讲故事，并且要靠自己讲，不要靠一堆无聊的幻灯片。如果你能做到这三点，你就取得了一半的成功。
