To Maslow, self-actualization is the ability to become the best version of oneself. Maslow stated, “This tendency might be phrased as the desire to become more and more what one is, to become everything that one is capable of becoming.” Of course, we all hold different values, desires, and capacities. As a result, self-actualization will manifest itself differently in different people. One person may self-actualize through artistic expression, while another will do so by becoming a parent, and yet another by inventing new technologies. Maslow believed that, because of the difficulty of fulfilling the four lower needs, very few people would successfully become self-actualized, or would only do so in a limited capacity. He proposed that the people who can successfully self actualize share certain characteristics. He called these people self-actualizers. According to Maslow, self-actualizers share the ability to achieve peak experiences, or moments of joy and transcendence. While anyone can have a peak experience, self-actualizers have them more frequently. In addition, Maslow suggested that self-actualizers tend to be highly creative, autonomous, objective, concerned about humanity, and accepting of themselves and others. Maslow contended that some people are simply not motivated to self-actualize. He made this point by differentiating between deficiency needs, or D-needs, which encompass the four lower needs in his hierarchy, and being needs, or B-needs. Maslow said that D-needs come from external sources, while B-needs come from within the individual. According to Maslow, self-actualizers are more motivated to pursue B-needs than non-self-actualizers.
