“Letter To Our World is a global #happiness project created to connect strangers from all over the world, to help us touch each other’s lives in a positive way. A map of the world made out of stamps will travel around the globe, to create a Letter To Our World with advice for a happier life.

To get involved with the project and be the one selected in your country to receive and sign your happiness advice on the map, just send us your definition of happiness in writing, and/or a video, and/or pictures to lettertoourworld@gmail.com (include your Twitter, age, city and country)”
