The Happiness Project Indonesia: Simplest act of kindness

"The Happiness Project Indonesia," initiated by Melliza Xaviera Putri Yulian, aims to help individuals discover true happiness beyond material success. Reflecting on the rise in depression and suicide rates, Melliza believes that happiness lies not in wealth, but in psychological well-being and self- actualization. The project began during her tenure as the 2019 Tourism and Creative Economy Ambassador of Jakarta, focusing on spreading happiness through social initiatives. These include collaborations with Ikatan Abang None Jakarta, food donations, cultural performances, and mental health awareness.
