"Twenty-five years of helping business leaders around the world develop ideas has taught me three things: 1. There is no more powerful way to come up with a new idea than to draw a simple picture. 2. There is no faster way to develop and test an idea than to draw a simple picture. 3. There is no more effective way to share an idea with other people than to draw a simple picture. While good speaking is engaging and inspiring, we need to recognize the limitations of our words. Let's be clear: there's nothing wrong with words. What's wrong is that they're not enough. This is where pictures come in. Whether drawing them, looking at them, or talking about them, pictures add an extraordinary amount to our ability to think, to remember, and to do."
