Intrinsic vs Entrinsic
The main difference between intrinsic and extrinsic motivation is the origin or place where the motivation comes from. In terms of purpose, they are the same in creating interest, maintaining focus, creating expected behavior, and an expected outcome.
Another major point of difference between the two types of motivation is the cause of each type. In terms of intrinsic motivation, rewards or incentives are usually self-based or things that occur inside a person. There can be numerous reasons, but they are all personal. On the other hand, extrinsic motivation needs to have an external reward or motive to perform a particular behavior.
