Read the story of the Salwens, an Atlanta family that decided to take the dramatic step of selling their house and donating half the value ($800,000) to The Hunger Project in Ghana. Although most of us are not in a position to do something that life-altering, this family's journey to giving back, chronicled in their book, The Power of Half, challenges us to think about what we can do without in order to make a difference for someone else. We'd love to hear your thoughts.
