The purpose of the study is to explore the antecedents of minimalism and, further, to study the impact of minimalism on millennials’ well-being via a sense of fulfilment. To understand the origins of minimalism and its following effects on well-being, a theoretical framework is created. An online survey with a structured questionnaire was created to collect the necessary data from respondents. SMART PLS was used to analyse the suggested framework. This research establishes the mediating role of a sense of fulfilment in the interactions between minimalism and well-being and shows how environmental awareness, contemporary aesthetics, voluntary simplicity, normative influence, and resource sharing positively lead to minimalism. A minimalist lifestyle will help to preserve precious resources, reduce waste, and lower carbon emissions, all of which will have a significant positive influence on the environment. Additionally, clearing up clutter will give them more room and time, which will improve their well-being because they will have more time for their family and interests. The study suggests a thorough model to comprehend the origins of minimalism. Additionally, it established a connection between well-being and minimalism.
