Both intrinsic and extrinsic motivation have their merits, but intrinsic motivation tends to have longer-lasting and more sustainable effects. Intrinsic motivation comes from within and is driven by personal satisfaction, enjoyment, or a sense of purpose. It can lead to higher levels of engagement, creativity, and job satisfaction. However, extrinsic motivation, such as rewards or recognition, can be effective in the short term and for specific tasks or goals. Combining intrinsic and extrinsic motivation can create a balanced approach that caters to individual preferences and maximizes overall motivation.
