Quizplus · Accepted Answer

Self-determination theory proposes that intrinsic motivation, which stems from personal interest and enjoyment, is a stronger determinant of behavior change and success than extrinsic motivation, which is driven by external rewards or pressures. In Julius' case, his previous attempts to lose weight motivated by extrinsic rewards did not lead to sustained behavior change until he found intrinsic motivation to do it for himself.
