Maslow's hierarchy of needs theory proposes that people are motivated to fulfill basic needs like physical survival and safety before moving on to social, esteem, and self-actualization needs. Self-actualization involves fulfilling one's potential and achieving a sense of accomplishment. While influential, Maslow's theory has been criticized for oversimplifying human motivation and lacking evidence that needs must be fulfilled sequentially as proposed. Overall, the theory suggests that self-actualized people are problem-focused, accept reality and themselves, act autonomously, and pursue creativity and fulfilling their potential.
