Motivation is a term that refers to a process that elicits, controls, and sustains certain behaviors. Motivation is a group of phenomena which affect the nature of an individual's behavior, the strength of the behavior, and the persistence of the behavior. For instance: An individual has not eaten, he or she feels hungry, as a response he or she eats and diminishes feelings of hunger. There are many approaches to motivation: physiological, behavioural, cognitive, and social.It's the crucial element in setting and attaining goals—and research shows you can influence your own levels of motivation and self-control . According to various theories, motivation may be rooted in a basic need to minimize physical pain and maximize pleasure, or it may include specific needs such as eating and resting, or a desired object, goal, state of being, ideal, or it may be attributed to less-apparent reasons such as altruism,selfishness, morality, or avoiding mortality. Conceptually, motivation should not be confused with either volition or optimism. Motivation is related to, but distinct from, emotion.
