It is interesting to note that he studied exemplary people such as Albert Einstein, Jane Addams, Eleanor Roosevelt, and Frederick Douglass rather than mentally ill or neurotic people, writing that "the study of crippled, stunted, immature, and unhealthy specimens can yield only a cripple psychology and a cripple philosophy."

Maslow's theory, also known as the, 'Hierarchy of needs' describes at least five sets of goals, which we may call basic needs. These are briefly: physiological, safety, love, esteem, and self-actualization.
"These basic goals are related to each other, being arranged in a hierarchy of prepotency. This means that the most prepotent goal will monopolize consciousness and will tend of itself to organize the recruitment of the various capacities of the organism. The less prepotent needs are minimized, even forgotten or denied. But when a need is fairly well satisfied, the next prepotent ('higher') need emerges, in turn to dominate the conscious life and to serve as the center of organization of behavior, since gratified needs are not active motivators. "
So, when you are at the cross roads of life and wondering - 'Why does the address, which once meant a hallowed precinct to me, is just another milestone in my life now?' -you probably are waiting to rise to the next higher datum plane of existence. Find it and be it.
