You can’t give a powerful new idea to an audience unless you can learn how to explain. That can only be done step by step, fueled by curiosity. Each step builds on what the listener already knows. Metaphors and examples are essential to revealing how an idea is pieced together. Beware the curse of knowledge! You must be sure you’re not making assumptions that will lose your audience. And when you’ve explained something special, excitement and inspiration will follow close behind.
