Abstract Sustainable development requires individuals to make mindful, long‐term choices that preserve the planet for future generations. Becoming a sustainable citizen involves awareness, responsibility, and a commitment to long‐term thinking—qualities that rely heavily on self‐control. Although self‐control is a limited resource, it can be trained and applied across various domains, contributing to healthier lifestyles and reduced environmental impact. Yet, this ideal faces strong resistance in societies that prioritize immediate gratification, consumerism, and comfort. Bridging the gap between sustainable intentions and actual behavior requires supportive social, educational, and institutional frameworks as proposed by the conceptual model of the two‐way dynamics of sustainable citizenship. By fostering environments that make self‐discipline easier and more meaningful, individual actions can eventually lead to collective change and the redefinition of societal norms. This suggests that effective sustainability policies should combine individual self‐control interventions with structural changes that reduce the cognitive burden of pro‐environmental choices.
