the 1940s. Maslow classified human needs into a five-tier pyramid, with the most basic needs at the bottom and the more complex ones at the top. The first level encompasses physiological needs, such as food, water, and shelter, which must be satisfied before an individual can focus on higher-level needs. Once these basic needs are met, the individual can pursue safety needs, which include personal security, health, and well-being. The next tier is the social needs, where relationships, love, and belonging play a crucial role. After social needs are fulfilled, individuals seek esteem needs, encompassing self-esteem, respect from others, and recognition. Finally, at the pinnacle of the pyramid, are self-actualization needs, representing personal growth, self-improvement, and the realization of one’s full potential. Maslow’s theory suggests that individuals are motivated to fulfill these needs in sequence, and the inability to meet lower-level needs can hinder one’s progress toward self-actualization. His work has had a profound impact on psychology, enhancing our understanding of human motivation and personal development.
