Maslow's hierarchy of needs is a psychological theory proposed by **Abraham Maslow** in 1943, depicting human motivations as a series of hierarchical levels within a **pyramid**. At the base are the most fundamental needs, which must be satisfied before individuals can attend to higher-level needs. The five levels of Maslow's hierarchy of needs, from the base to the peak of the pyramid, are: 1. **Physiological**: These are the basic necessities for human survival, such as air, water, food, shelter, and sleep. Without these, the human body cannot function properly. 2. **Safety**: Once physiological needs are met, the need for safety and security becomes prominent. This includes personal security, financial security, health and well-being, and safety against accidents or illness. 3. **Love and Belonging: After physical and safety needs are fulfilled, social needs emerge. This level pertains to emotional relationships, including friendships, romantic attachments, family, and social groups, emphasizing the importance of belongingness and affection. 4. **Esteem**: With the first three levels satisfied, esteem needs become more significant. This category includes self-esteem, confidence, achievement, respect of others, and the need to be a unique individual. It is divided into two parts: (a) esteem for oneself (dignity, achievement, mastery, independence) and (b) the desire for reputation or respect from others (status, prestige). 5. **Self-Actualization**: At the peak of Maslow's hierarchy, self-actualization refers to the realization of an individual's potential, self-fulfillment, seeking personal growth and peak experiences. This stage is about becoming the most that one can be and is often described as the pursuit of personal goals and fulfillment of personal capabilities.
