I can’t dance. But I love watching people who can, people whose limbs all go where they’re supposed to and who look like they’re having too much fun to feel self conscious.

There are a lot of people like me, who feel inspired by people who do what they love and do it with joy.

I think that’s the secret behind some of the most popular viral videos on the Internet: JK Wedding Entrance Dance, for example, or Caine’s Arcade, or Isaac Lamb’s lip-dub proposal.

The videos are cute. They’re fun. We smile when we watch them. But what makes us share them?
