Maybe it’s a promise to say good morning to three strangers, an inspirational quote, a kind word, a hug.

Live Happy magazine once again is setting up more than 70 large orange happiness walls, including two in metro Atlanta, in a campaign campaign designed to help spread joy in simple acts of kindness.

As part of the #HappyActs campaign, Live Happy is hoping the happiness walls will be central points, even gathering spots, for people to pledge — and reflect on — how they will share happiness with others.

Sunday is “Interntional Day of Happiness” March 20.

This is the third year these happiness walls have been set up in metro Atlanta. People are also encouraged to spread cheer through via social media on virtual happiness walls to advance the efforts.

The happiness wall will be set up at Atlantic Station Saturday. On Sunday, a happiness wall will be set up at Andretti Karting in Marietta.
