Motivation refers to the driving force or inner desire that compels a person to act or behave in a particular way. It is the internal or external stimulus that energizes and directs behavior towards a specific goal or objective. Motivation can arise from a variety of sources, including basic physiological needs such as hunger or thirst, social needs such as the need for acceptance and belonging, or personal aspirations such as achievement or self-fulfillment. Motivation can be intrinsic, meaning it comes from within a person, or extrinsic, meaning it comes from external rewards or punishments. Effective motivation can lead to increased productivity, engagement, and goal attainment.
