Low sustainability of livelihood is concerning. I explored the proactive actions of street vendors in turning their adversities into resilience. I interviewed 9 purposively selected street food vendors. I analyzed their perception via thematic analysis. I am convinced that vendors face economic, regulatory, and physical adversities, which they address through self-driven actions, support networks, and reliance on faith, leading to resilience expressed in persistence, continued livelihood efforts, and livelihood sustainability driven by family motivation. I support the implementation of policies and programs that support vendors, including inclusive vending regulations, livelihood assistance, health and safety support, and the strengthening of community-based networks and institutional support systems. My study opens possibilities for multiple linear regression and mediation analysis to examine relationships among adversities, protective systems, and resilience, and develop validated instruments using Exploratory Factor Analysis.
