All of us face hard choices in our lives. Some face more than their share. We have to decide how to balance the demands of work and family. Caring for a sick child or an aging parent. Figuring out how to pay for college. Finding a good job, and what to do if you lose it. Whether to get married--or stay married. How to give our kids the opportunities they dream about and deserve. Life is about making such choices. Our choices and how we handle them shape the people we become. For leaders and nations, they can mean the difference between war and peace, poverty and prosperity.
