Brendan Kennelly wrote, If you want to serve your age, betray it. But what does it mean to betray your age? It means expose its lies, humiliate its conceits, debunk its arrogance, and question its certainties. Nick Cooney does this exquisitely. I would like his book to be in every school library and private bookshelf. But most importantly, I would like his words to be inscribed on the hearts of everyone who looks at the face in the mirror each morning and resolves to do all they can to make life better for the powerless. I am full of admiration for this young man. Philip Wollen, retired Vice-President, Citibank Too often, charity makes us feel good but fails to do good. This timely, thoughtful book shows how our contributions can make a bigger difference. Adam Grant, Wharton professor and New York Times bestselling author of Give and Take: Why Helping Others Drives Our Success Nick Cooney is great at explaining How To Be Great at Doing Good and I hope his book will be widely read.

Shushana Castle, Securities Specialist, Sovereign Investments, and former Board member of the Clinton Climate Initiative For anyone looking to make the world a better place, I highly recommend considering the arguments presented in How to be Great at Doing Good. We're accustomed to trying to get the most for our money, but donating is the area where this principle is perhaps most important and least appreciated. Holden Karnofsky, Co-Founder and Co-Executive Director, GiveWell.org Do you know that some charitable programs and organizations are thousands of times more effective than others (and not just because there are scams)? If you want to know who s doing the most good, this book will give you the tools to make accurate assessments. If you want to get the most bang for your buck, this book will show you the way. John Robbins, author of Diet For A New America, and President of The Food Revolution Network Giving money to a social cause isn't merely a donation to charity; it's an investment. It won't yield a financial dividend, but the return-on-investment comes in the form of the kind of social change the investor wants to affect. Nick Cooney helps such philanthropists decide how they can get the biggest bang for their donated buck in this very worthwhile and clearly-written book.
