Abraham Maslow was an American psychologist best known for creating the Maslow's Hierarchy of Needs, a theory that explains human motivation. He proposed that people are motivated by a series of needs, starting from basic physical requirements like food and safety, and moving up to higher-level needs such as love, esteem, and self-actualization. This model helps us understand how individuals prioritize their needs in life. Maslow believed that once basic needs are met, people can focus on personal growth and fulfillment. His ideas have influenced various fields, including psychology, education, and business, encouraging a more holistic approach to understanding human behavior and motivation.
