Here’s what Wikipedia has to say about motivation:
“Motivation is a psychological feature that arouses an organism to act towards a desired goal and elicits, controls, and sustains certain goal-directed behaviors. It can be considered a driving force; a psychological one that compels or reinforces an action toward a desired goal. For example, hunger is a motivation that elicits a desire to eat. Motivation is the purpose or psychological cause of action.”
Motivation has been shown to have roots in physiological, behavioral, cognitive, and social areas. Motivation may be rooted in a basic impulse to optimize wellbeing, minimize physical pain and maximize pleasure. It can also originate from specific physical needs such as eating, sleeping or resting, and sex.
Motivation is an inner drive to behave or act in a certain manner. “It’s the difference between waking up before dawn to pound the pavement and lazing around the house all day. These inner conditions such as wishes, desires, goals, activate to move in a particular direction in behavior.”
That’s a pretty good explanation, but let’s keep it a lot shorter.
Motivation is finding the energy and enthusiasm to accomplish your goals.
