The Giving Keys

When singer-songwriter and actress Caitlin Crosby got on stage with her hotel key conveniently draped on a makeshift chain around her neck, she had no idea that this would eventually open a door and lead to "The Giving Keys". This organization unlocks human potential through a circle of passed-on keys inscribed with inspiring words like "courage", "trust", and "love". Both givers and recipients of the keys share stories online in this pay-it-forward ecosystem. But perhaps the greatest testament to the power of the keys is its ability to transform the lives of their creators: homeless people who have, by way of lovingly crafting messages on pieces of metal, found self-esteem, education, employment, and keys to a brighter life.
