A chronic illness or physical challenge can be devastating. A diagnosis of cerebral palsy, lupus, diabetes, multiple sclerosis, cancer, or any number of other diseases and disorders can seem like a death sentence, a storm cloud forever hanging over one's head. Some people give in to their illness, giving up hope and the will to fight. Others choose to make the best of their situation, facing their adversity head-on, displaying a courage and determination they may not really feel. The contributors to Silver Linings, however, have gone a step further. They have not only decided to fight their respective disabilities, but have dedicated their lives to making the world better for those around them.
