An advantage (relative to extrinsic motivation) is that intrinsic motivators can be long-lasting, self-sustaining, and satisfying. For this reason, efforts in education sometimes attempt to modify intrinsic motivation with the goal of promoting future student learning performance, creativity, and learning via long-term modifications in interests. Intrinsic motivators are suggested to involve increased feelings of reward and thus may support subjective well-being. By contrast, intrinsic motivation has been found to be hard to modify, and attempts to recruit existing intrinsic motivators require a non-trivially difficult individualized approach, identifying and making relevant the different motivators needed to motivate different students, possibly requiring additional skills and intrinsic motivation from the instructor.
