It's interesting how people find their purpose when they least expect it. One wrong turn led Luma Mufleh, who is a Jordanian immigrant, to run into a soccer game with a group of refugee children from different countries in Clarkston, GA; she asked if she could join. When these kids were playing soccer, they could forget about their problems and their past, even for a few minutes. This inspired Luma to develop a soccer program for refugee kids, and later a school tailored to educating refugees. Since 2004, her nonprofit, the Fugees Family, has helped more than 1,000 refugee children.
Take a look at Luma Mufleh's TED talk and this New York Times article about her work.
