The HBR Guide to Persuasive Presentations by Nancy Duarte teaches how to create presentations that convince people to take action. She stresses that a successful presentation is not just about communicating information but about persuading your audience to agree with you. By focusing on your audience's whys, you can create a message that deeply resonates with them and enable action.

Duarte explains how to structure your presentation like a story, with a beginning, middle, and end that captures attention and takes the audience on a journey. Clear and focused messaging, along with visual aids, are important elements. The aim is to emotionally and logically connect with your audience so that they feel compelled to act on your message.

The book also provides practical tips on delivery, including how to handle anxiety, maintain high energy levels, and use body language effectively. Duarte's advice is about making your presentations memorable and persuasive by ensuring your message is clear, well-structured, and delivered confidently.
