The introduction of the book makes it clear that consumption is more than just a means of satisfying needs—it is an integral part of our self-concept, our social relationships, and our cultural identity. In a world where advertising and social media dominate our everyday consumption, reflecting on consumption habits becomes all the more important. Addiction to consumption is examined as a serious issue that has not only individual but also societal causes. In this context, consumption is understood as culturally normalized behavior that shapes identity, status, and group affiliation. The introduction makes it clear that consumption habits are not solely the result of individual choices, but are also promoted by social and economic structures. The guide aims to help readers think more critically about their own consumption behavior and to develop practical strategies for change.
