Self-actualization is a concept in psychology that represents the highest level of psychological development where an individual's potential is fully realized. It is closely related to motivation as it is considered the ultimate goal that motivates behavior. According to Abraham Maslow's hierarchy of needs, self-actualization sits at the top of the pyramid of human needs and is pursued once more basic needs are fulfilled. This concept suggests that individuals are motivated to achieve their full potential and express their true selves once their basic and psychological needs are satisfied.
