Maslow's Hierarchy of Needs is a psychological theory that outlines the stages of human motivation. It is often depicted as a pyramid with five levels. At the base are physiological needs, such as food and water, which must be met first. Once these basic needs are satisfied, individuals can focus on safety needs, like security and stability. As people progress up the pyramid, they seek social needs, including love and belonging, followed by esteem needs, which involve self-respect and recognition. At the top is self-actualization, where individuals strive to reach their full potential and pursue personal growth and fulfillment.
