Motivation is the driving force behind an individual's actions, thoughts, and behaviors. It is the desire or willingness to do something, often influenced by internal or external factors such as personal goals, values, rewards, or consequences. Motivation can come from a variety of sources, including intrinsic factors like passion and curiosity, as well as extrinsic factors like money or recognition. It plays a crucial role in goal-setting, productivity, and overall well-being.
