Government economists define durable goods as products that last three years or more.
Durable living is a dedication to designing and purchasing products that will last and satisfy for a lifetime. Products that serve their owners instead of the other way around. Products that reduce worry because they can be relied on.
Durable living is not necessarily the same as simple living or frugal living. Although simplicity often goes along with durability, and the simplest and most worry-free product is the one you don't have at all, people do have needs and desires. And although durable products are often cheaper in the long term, they can be much more expensive than disposable consumer goods in the short term.
