Our stuff says things about us. They present symbols and communicate cultural messages on our behalf. The following could help visualize this better:
The guy in the Porsche sports car versus the dad in a Toyota Corolla.
The well-dressed lady with the designer handbag versus the female wearing a school backpack, sweater, and jeans.
We subconsciously are attracted to the things that reflect our tastes and worldviews, and what we buy into are representations of ourselves.
