We can change the world starting with ourselves! In these circumstances it's important to remember what makes us happy and stimulate our positive feelings. The International day of happiness is a perfect opportunity to do so. Regarding that day, we have come to various activities that we would like to share and spreed. We would like to make materials that can be presented in schools to help us remember to empower our positive feelings even after the International day of happiness. Together with that, we will provide some materials to connect activities with mental health and positive development topic.
