"Own Less, Be More" originated from a moment of sharing among three youth workers who met during a Training Course in Denmark in 2019. One of them, particularly engaged in sustainability and green practices, shared her concerns about the relationship between young people and material goods. This conversation sparked a collective desire—and a recognized need—to investigate the topic on an international level, exploring how young people relate to material possessions and the motivations behind their attachments. To address these concerns, 17 empathetic interviews were conducted with young people across Europe to identify their needs and perspectives. Based on the insights from these interviews, a survey was developed and disseminated, with the support of European youth workers active in materialism and sustainability. These youth workers, who later became group leaders in the project, shared the survey with local young people from six communities in Italy, Spain, Denmark, Poland, Greece, and Romania. The results confirmed the interest of young people in the topic and their strong desire for an educational opportunity to help them rethink their attitudes toward material goods. This groundwork laid the foundation for the project, shaping its structure and partnership. Group leaders collaborated with local youth to design activities aligned with their interests, ensuring that the Youth Exchange met their needs. The project engaged 30 young people (4 participants per country, plus 1 group leader each) in an 8-day youth exchange held at Casa a Colori in Dolo, Italy, from September 4 to 11, 2023. The objectives were: *To provide participants with knowledge about minimalism and sustainability as tools to rethink their relationship with material goods, their impact on the planet, and personal self-development. *To raise awareness of the human and environmental impacts of materialistic and consumerist choices. *To equip participants with practical tools for self-development and sustainable living, empowering them to overcome consumerism and materialism. During the Youth Exchange, participants were guided through a reflective learning process. They examined their habits and the meaning they attached to material possessions, identifying changes they could make to develop a more balanced relationship with these goods. Activities focused on practical sustainability practices such as recycling, reusing, and upcycling, complemented by a workshop and visit from Malefatte Venezia, a cooperative that transforms recycled materials into ethical and sustainable products. This visit provided participants with tangible examples of how sustainable practices can be implemented in creative and impactful ways. The exchange emphasized experimentation and self-discovery, enabling young people to find their unique approach to sustainability and contribute actively to the planet's sustainable development. By focusing on meaningful possessions and detaching personal happiness from material goods, participants developed a more genuine relationship with what they own and a greater appreciation of their individual contributions to a sustainable future.
