Intrinsic Motivation: It is defined as the process of executing a behavior or an action by an individual because he or she enjoys the activity. The individual gets the inspiration for acting himself or herself.

Extrinsic motivation: It is defined as the behavior of a person that is operated by external rewards, for example, fame, praise, money, and grades. In this case, the motivation originates from outside of the person.
