The 21-Day Kindness Challenge launched September 11th and culminated on the eve of Mahatma Gandhi's birthday. Close to 6000 people across 98 different countries around the world signed up to collectively unleash a tidal wave of good. Their stories inspired many -- including young rapper-activist "Nimo" Patel at the Gandhi Ashram in India. Nimo wasted no time channeling that inspiration into an infectious music video. "Being Kind" was created on super short notice by an intercontinental crew of volunteers working out of their living rooms. It features footage from all over the world and heart-melting appearances by the children Nimo works with in the slums. Watch, listen, and prepare to smile big at this lyrical reminder that kindness really is "all we can leave behind."
