In the mid-20th century, psychoanalysis theory and behaviorism theory were very prominent in the field of psychology. Although these two views are quite different, they all have a general assumption that people are driven by forces beyond their control. In response to this hypothesis, a new view has emerged, that is, humanistic psychology. Humanists hope to provide a more optimistic and positive perspective for human struggle. The theory of self-realization is based on humanism. Humanistic psychologists believe that human beings are driven by higher needs, especially the need to realize themselves. Unlike psychoanalysts and behaviorists who focus on psychological problems, Maslow developed his theory by studying individuals with mental health. Maslow put his theory of self-realization at the level of need. This hierarchy represents five needs, ranging from low to high: physiological needs: those that keep us alive, such as food, water, shelter, warmth and sleep. Safety needs: A sense of security, stability and fearlessness are needed. Love and belonging needs: the need to belong to society by developing relationships with friends and family. Self-esteem needs: Need to feel (a) self-esteem based on one’s own achievements and abilities and (b) recognition and respect from others. Self-fulfillment needs: the need to pursue and realize one’s own unique potential. When Maslow first explained the hierarchy in 1943, he pointed out that higher demand would not normally be pursued until lower demand was met. However, he adds that there is no need to fully meet someone’s next need to move to a hierarchy. On the contrary, these needs must be partially met, which means that a person can pursue all five needs at the same time at least to some extent. Maslow included warnings to explain why some people might pursue higher needs rather than lower ones. For example, some people who are particularly motivated by creative expression of their desires may pursue self-fulfillment even if their lower needs are not met. Similarly, those who are particularly committed to pursuing higher ideals may achieve self-fulfillment, although adversity prevents them from meeting their lower needs. For Maslow, self-actualization is the ability to be the best version of himself. “This tendency can be expressed as a growing desire to be who you are and what you can be,” Maslow said. Of course, we all hold different values, aspirations and abilities. As a result, self-actualization can be manifested differently in different people. One can achieve self-realization through artistic expression, while the other can achieve it by becoming a parent, while the other can achieve it by inventing new technologies. Maslow believes that because of the difficulty in meeting these four lower needs, few people can successfully achieve self-realization, or can only achieve within a limited capacity. He argues that people who can successfully self-actualize have certain characteristics. He calls these people self-actualizers. According to Maslow, self-actualizers share the ability to experience peak times, or to enjoy and transcend moments. Although anyone can have peak experience, self-actualizers are more frequent. In addition, Maslow believes that self-actualizers tend to be highly creative, autonomous, objective, concerned about human nature, and accepting themselves and others. Maslow argues that some people simply have no motivation to achieve themselves. He illustrates this by distinguishing defective requirements, or D-requirements, including four lower requirements at his level, and as requirements, or B-requirements. Maslow said that D-demand comes from external sources, while B-demand comes from internal sources. According to Maslow, self-actualizers are more motivated to pursue B-needs than non-self-actualizers.
