"What is the book that changed your life? (not novels or religious texts)"
I think it's a wonderful way to connect in a less superficial way and learn a little more about each other. It's also a wonderful way to discover new books worth reading.

John G. Miller
Who Moved My Cheese? showed readers how to adapt to change. Fish! helped raise flagging morale. QBQ! The Question Behind the Question addresses the most important issue in business and society today: personal accountability. In today's business culture, the lack of personal accountability is a problem that has resulted in an epidemic of blame, complaining and procrastination. Company goals are achieved through individuals asking themselves how they can contribute and make a difference, not through paying lip service to teamwork. Using succinct, light-hearted stories, Miller offers a practical and inspirational method for putting personal accountability into daily action that can bring incredible results: problems get solved, internal barriers come down, service improves, teamwork grows and people adapt to change more quickly.
