Tad Waddington has pulled together the great thoughts from the great thinkers who worried about why we are here, what we are supposed to be doing, and how best to get on with it. These are big, tough questions but they are tackled, in an amazingly compact and thought-provoking way, so that everyone can arrive at their own answers. Waddington has a special gift that allows you to see his thoughts clearly at work—yet he provides plenty of space for you to compare your ideas with history's best. Highly recommended for anyone looking for answers to life's most intriguing questions, brought to you by a uniquely talented guide, in a book you won’t be able to put down. Should be required reading for every senior executive everywhere in the world.

Yeats reflected upon his intellectual life and found it “a preparation for something that never happens.” Waddington offers us a contrast – a reflection upon preparation for what is happening.
—Ted Hayes, PhD, Principal Research Scientist, The Gallup Organization
In this wide-ranging and thought-provoking book, Waddington weaves a compelling intellectual tapestry. His thesis is as simple as it is profound: We can and should make a positive difference in our world. This little book is full of big ideas. Read it!
—James Gross, Associate Professor, Department of Psychology, Stanford University
Want to make a lasting impact? Waddington's book will get you there. Forget the lure of quick fixes and best practices that were designed for someone else. Waddington clearly explains how to understand the true nature of your problem and, more importantly, how to systemically think through a solution that will have lasting impact. Waddington combines ancient and contemporary theories of thinking, management, and innovation with practical examples of real life situations. A must read for anyone who wants their decisions to have purpose and impact.
—Bradley Kolar, CLO, University of Chicago Hospitals
Tad Waddington is an erudite and engaging writer. He uses the concepts of ancient Greek philosophy along with insightful modern quotations and anecdotes to show how people can shape their strivings into enduring contributions to humanity.
—Frank Schmidt, Ralph L. Sheets Professor, Department of Management and Organizations, University of Iowa
Tad Waddington boldly makes the case for a purposeful life, for making a deep and lasting positive impact in the world. More than that, he explains the habits of mind, problem solving processes and life practices that make it possible to make the most of our individual skills, passions and power. His book is inspiring, empowering, and deeply useful for everyone considering which road to take, or whether to blaze a new trail. I refer to it regularly for guidance and inspiration.

Be inspired. Make a “lasting contribution.” Read this book. Twice.
—Marvin Zonis, Professor, Graduate School of Business, University of Chicago
By tying together intellectual principles and pragmatic effectiveness in such commonsense terms, Tad Waddington has produced a work worth reading, rereading, and pondering, especially in our times when “in the realm you care about, the human realm, the nature of the world matters less than the stories you tell yourself about the nature of the world.”
—Timothy C. Wong, Professor of Chinese, Arizona State University.
