With the implementation of the MentaHack international youth exchange, the organizers set out to achieve a complex and multifaceted goal that simultaneously addresses the mental, digital, and environmental challenges faced by today's youth, while aligning with the priorities of the Erasmus+ programme. The project's objectives were interlinked to create a supportive, inclusive, and developmental learning environment in which participants gained not only knowledge but also experiences, skills, and meaningful community connections. The primary aim of the programme was to strengthen youth communities. The organizers fostered an atmosphere where young people could feel safe, express themselves freely, and actively participate in group decision-making. This collective experience held particular significance for those from disadvantaged backgrounds, as the project provided them with a tangible experience of social inclusion. A key goal was the development of new skills related to mental health, digital competence, and a sustainability-oriented mindset. The young participants not only received theoretical knowledge—such as on stress management, mindfulness, or data protection—but also learned techniques and perspectives through first-hand experiences, supporting their well-being and mindful presence in both the digital and physical world. One of the strengths of MentaHack was its innovative blend of traditional youth exchange methods with creative tools. Participants explored digital and artistic instruments that enabled them to process and express their thoughts and experiences in creative ways. This supported the development of their critical thinking, self-expression, and self-awareness. Activities included digital workshops, thematic interactive games, and nature-based creative work, all designed to facilitate learning and reflection. Moreover, the project was consciously designed to ensure that the acquired knowledge and experiences would not end with the 10-day programme. Participants took an active role in documenting and evaluating their own learning journey using Youthpass journals and created specific action plans to share their new knowledge within their local communities. Through this, the project aimed to generate long-term impact by empowering young people to act with greater mental resilience, digital awareness, and environmental responsibility within their own environments. MentaHack clearly contributed to the horizontal objectives of Erasmus+ related to inclusion, digitalisation, environmental awareness, and active participation. It provided equal opportunities for young people with fewer opportunities while promoting European identity, intercultural understanding, and social cohesion. The methodologies used were in line with the principles of quality youth work and helped to strengthen partnerships between the participating organisations, laying the groundwork for future joint initiatives. MentaHack was not merely a thematic youth exchange, but a comprehensive learning and community experience that led to personal development, social impact, and organizational progress alike.
