That piqued my interest and remained so to this day. Marketers use the hierarchy of needs to understand a customer’s psyche to evaluate their motivations when they shop for things they need or want.
This hierarchy ranges from more concrete physical needs such as food and water, rising to emotional needs, and to more abstract concepts such as personal growth and self-fulfillment.
Like most living things, humans are motivated first and foremost by our survival. It would be hard to excel at anything else without satisfying our living needs. At the bottom of the pyramid is the lowest level that applies to our physiological needs to survive life.
