Have you ever seen the viral YouTube video of a guy doing a funky dance by himself at the 2009 Sasquatch Music Festival? Regardless of how many people were staring at him, he continued to embrace his joy, wildly shaking his hips and arms.
A few minutes later, another guy got up to join him. The two of them let loose and became a beacon of joy. Shortly after, more and more people joined their spontaneous dance party. Eventually, a whole crowd celebrated joy together. And because someone filmed it and shared it online, now more than 23 million people have been inspired by this moment of joy.
