Self-Actualization

In Abraham H. Maslow’s theory, an actualization of one’s potential arrived at by satisfaction of a hierarchy of needs visualized as a pyramid. At the base are biological or survival needs; the next step up is the need for friendship and affiliation; finally, there is an assurance of self-worth, which comes from giving and receiving love and from an internalized sense of self-esteem. In Maslow’s view, abnormal or dysfunctional behaviour results from a failure to attain the self-esteem necessary to achieve self-actualization.
