Can you choose to be happy?

Are you happy? How would you answer that question if a stranger with a camera asked? Five years ago, filmmaker Atdhe Trepca quit his job and drove across the country with a camera, asking hundreds of people that question. His videos reach millions on TikTok and Instagram, and now he’s made a documentary. Today, Optimist reporter Maggie Penman shares what Trepca has learned – and the research that backs up his observations. If you want to hear more stories like this, please let us know.
