Maslow's theory posits that human needs follow a hierarchical structure where basic needs propel the individual to seek higher needs. Humans, therefore, are motivated by the intrinsic need for self-actualization. According to Maslow's theory, physiological needs, such as food and water, are the basic needs of an individual required to sustain life. After fulfilling their physiological needs, an individual strives for the next stage that focuses on safety and security needs and where they attempt to avoid the risk of physical and emotional harm. Once the lower levels have been satisfied, a person tries to meet the higher levels. Social needs involve the need to love and be loved. It gives a sense of belonging and acceptance. For example, having a close group of friends. The need to feel important develops when a person experiences a sense of belonging. Self-esteem is the need for respect from others, and self-respect includes competence, self-confidence, and independence. At the highest level of Maslow's hierarchy of needs is self-actualization. It represents the need to reach one's greatest potential through personal development and acceptance of oneself and others. It can only be achieved once other human needs are met.
