Maslow's Hierarchy of Needs is a theory of human motivation that describes how humans prioritize their needs. The hierarchy is often depicted as a pyramid, with the most basic physiological needs at the bottom and the highest needs for self-actualization at the top. The five levels of needs are:
According to Maslow, people are motivated to fulfill lower-level needs before they can move on to higher-level needs. Once a lower-level need is satisfied, it no longer serves as a motivator, and individuals become motivated to satisfy the next higher-level need.
These are the most basic needs for survival, such as food/nutrition, water, shelter, clothing, and sleep. 
Once physiological needs are met, people seek safety and security, including personal and financial security. Freedom from fear, structure, order, law and limits. 
People have a need for social interaction, love, and belonging, and they seek to establish relationships with others.
People have a need to feel respected and valued by others and to have a sense of self-esteem and self-worth.
The highest level of need is the need for self-actualization, which
involves realizing one's full potential and pursuing personal growth and
fulfillment. This includes understanding, beauty, morality, exploration, and play.
