Self-Actualization as The Ultimate Desire

It was 1943 when psychologist Abraham Maslow first introduced the concept of what we've later come to know as Maslow's Hierarchy of Needs, by writing about it in an American Academic Journal called Psychological Review. This seemingly simple pyramid listing human needs in a hierarchical order has become, nowadays, a widespread theory of psychological value, considered a point of reference in the field of psychology and taught in business and marketing schools all around the globe — although Maslow didn't mention any pyramid in the paper, and this theory is not backed by significant scientific evidence —.
