'Jane The Virgin' Actor Justin Baldoni Starts a Happiness Movement

Jane the Virgin's Justin Baldoni is spreading happiness.

Starting a social campaign called the "Good 30," the 30-year-old actor is sharing a video that he hopes will inspire people to make others happy.

In the video, Baldoni talks about why he and his best friends are starting the new social movement, saying, "We've spent our lives trying to make content that makes people happy. We believe that it's our job to create a better world, and it starts with each of us."

All money that gets donated to the campaign will go to the Zach Sobiech Osteosarcoma Fund. After losing two of his close friends to Osteosarcoma, Baldoni says that he learned a valuable lesson. That message is, "Happiness is not a limited resource."

The lesson was so powerful for Baldoni that he got it tattooed, and it has inspired him to bring more happiness to the world.

Now inspiring others, Baldoni has already made many people happy, including ET's very own Nancy O'Dell on set yesterday.

He gave the Clemson University alum a signed Dabo Swinney football.

We can't wait to see how much more happiness spreads over the next 30 days!
