The Hierarchy of Needs is a psychological theory proposed by Abraham Maslow in 1943. It suggests that human needs are arranged in a five-tier pyramid, starting from basic physiological needs like food and water, to higher-level needs such as safety, love, esteem, and self-actualization. Individuals must satisfy lower-level needs before they can focus on higher-level ones. This model emphasizes that unmet basic needs can hinder personal growth and fulfillment. For example, if someone is struggling to find food, they are less likely to seek social connections or pursue personal goals. Understanding this hierarchy helps in recognizing the importance of addressing fundamental needs for overall well-being.
