🔑:Maslow's hierarchy of needs is a psychological theory that classifies human needs into a five-tier model. The levels, from bottom to top, include physiological needs (food, water), safety needs (security, health), love and belonging (relationships, friendships), esteem needs (self-esteem, recognition), and self-actualization (personal growth, fulfillment). Individuals aim to fulfill lower-level needs before addressing higher-level ones.
