From the “I have a dream” speech to Steve Jobs’ iPhone launch, all great presentations have a common architecture. At TEDxEast, Nancy Duarte draws lessons on how to make a powerful call-to-action.

Nancy Duarte believes that ideas are the most powerful tools people have. Her passion is to help every person learn to communicate their world-changing idea effectively. “An idea is powerless if it stays inside of you… If you communicate an idea in a way that resonates, change will happen.”
