Stewart's behavior in that interview is most likely motivated by "the incentive of wanting to earn a high salary".
Extrinsic motivation alludes to conduct that is driven by outside remunerations, for example, cash, notoriety, evaluations, and acclaim. This sort of motivation emerges from outside the person, instead of intrinsic motivation, which starts within the person.
Individuals who are extrinsically motivated will keep on playing out an activity despite the fact that the undertaking probably won't be all by itself fulfilling.
