...frugality is an exchange: You’re trading the things you don’t value for things that you do value... Consider the human hierarchy of needs as described by Abraham Maslow. To put it simply, once one’s basic needs are met—clothing, food, shelter, companionship—humans then tend to have higher aspirations, such as self-actualization and professional fulfillment. This hierarchy is subverted in many ways—advertising, peer pressure, our own psychology—and it leaves us taking actions that undermine our basic needs while making futile attempts at grabbing at our higher needs.
