The 21-Day Kindness Challenge launched on September 11th, 2013. 98 countries. 6000 people. And a collective tidal wave of good that 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." Learn more about the movement at kindspring.org.
