Flourishing has emerged as a central concern in global youth development research. However, existing frameworks are predominantly informed by Western, individualistic paradigms, limiting their applicability across culturally diverse and collectivist contexts, particularly in the Global South. This study addresses this gap by exploring how young people in Uganda and India, two culturally rich collectivist societies, conceptualize and experience flourishing in their everyday lives. Adopting a qualitative research design, the study conducted in-depth interviews with 16 Ugandan and 21 Indian youth. Data were analyzed thematically using MAXQDA software. Flourishing was approached as a holistic construct, encompassing emotional, psychological, relational, societal, and spiritual dimensions. Findings revealed that Ugandan participants emphasized spiritual devotion, personal fulfillment, societal interdependence, academic and community engagement, and concerns about inadequate government support. Indian participants, while also grounded in a collectivist context, focused more on psychological resilience, educational aspirations, self-efficacy, and strategies for overcoming systemic barriers. These culturally distinct narratives underscore the complex, context-specific nature of flourishing. The study highlights the importance of developing culturally grounded frameworks for youth development and mental health, particularly in underrepresented regions. By centering the voices of youth in Uganda and India, this research contributes to a more inclusive and globally relevant understanding of human flourishing.
