“How do you predict what kind of society we’re in?  How do you know when’s the right time to make a difference? In Pendulum, Roy H. Williams and Michael R. Drew have combed through history’s ups and downs and the cultural shifts that ripple through every generation. They’ve written a unique guidebook that has an interesting perspective for marketers, entrepreneurs, and anyone is thinking about how to live in the now—and in the future.”

“Pendulum may be the most important book you read all year. This is not a book about business but one about how culture has changed, which will dramatically alter the way you must do business. It will open your eyes to exactly what is happening in the world today and how your business must respond. “
—Eric Rhoads, Publisher, Radio Ink

“We’ve all heard how history repeats. Now we know why. We humans swing from selfish to social every generation or so, and civilization swings with us. In their surprising, insightful and witty new book, Pendulum, Roy H. Williams and Michael Drew explain us to us. They explore the real reasons behind some of civilization’s greatest advances—and retreats. They show us why we repeat ourselves—but they also give us the tools that might prevent future catastrophes.”
—Robert J. Hughes, former Wall Street Journal reporter and author of Late and Soon
 
“Times change, but some things remain consistent: People either think of themselves or of others. The question is, how do you know when (and what does it mean) Roy H. Williams and Michael R. Drew have figured that out in Pendulum, their razor-sharp look at cultural shifts over the last 3,000 years (and the next ones too). Whether you try to come up with a new dish at KFC, a special pie at Pizza Hut or a menu change at Taco Bell, you need to know your customer. Pendulum gives you that knowledge.”
