“ High performers whom exhibit tremendous self-control tend to be burden by their own competence. Studies indicate that being extraordinary competent can place a person under an unusual amount of stress because it raises other people’s expectation of them. The more task that an exemplary employee produces with a ‘go-getting personality’ while maintaining high quality relationships with peers and clients, the more an organization tends to underestimates their actual effort and the more it expects of them. Other people do not comprehend how difficult it is for a high performer to complete multifaceted tasks. They also tend to underestimate how much effort an enterprising person exerts who maintains a positive and pleasant attitude while completing difficult assignments. ”
