Motivation is the internal process that initiates, directs, and maintains human behaviour toward the achievement of goals. It is one of the most important concepts in psychology because it explains why people think, act, and persist in certain ways. Every behaviour, whether simple or complex, is influenced by some form of motivation. A student studies to achieve good grades, an athlete trains to win competitions, and a worker performs tasks to earn income and gain recognition. Motivation gives energy to behaviour, determines its direction, and helps individuals continue their efforts even when they face difficulties. Psychologists describe motivation as a dynamic state that arises from the interaction of biological, psychological, emotional, cognitive, and environmental factors. Human needs, desires, interests, values, and expectations all contribute to motivation. It is not directly visible but can be understood by observing behaviour and the goals individuals try to achieve. Motivation changes with time and situations. A person may be highly motivated in one activity and show little interest in another depending on personal needs, experiences, and environmental conditions. The nature of motivation can be understood through several important characteristics. First, motivation is goal-oriented because every motivated behaviour is directed toward achieving a specific objective. Second, it is continuous and dynamic, as human needs and desires change throughout life. Third, motivation varies in strength from one individual to another and even within the same individual under different circumstances. Fourth, motivation may be conscious or unconscious. People are often aware of their motives, but sometimes hidden desires and emotions also influence behaviour. Fifth, motivation helps in maintaining persistence and effort. Individuals who are strongly motivated continue working despite obstacles and failures. Finally, motivation influences learning, performance, emotional well-being, creativity, and overall personality development. One of the major types of motivation is intrinsic motivation. Intrinsic motivation refers to engaging in an activity because it is enjoyable, interesting, or personally satisfying. The
