People who believe they have the power to exercise some measure of control over their lives are healthier, more effective and more successful than those who lack faith in their ability to effect changes in their lives.

Perceived self-efficacy also shapes causal thinking. In seeking solutions to difficult problems, those who perceived themselves as highly efficacious are inclined to attribute their failures to insufficient effort, whereas those of comparable skills but lower perceived self-efficacy ascribe their failures to deficient ability

If you look at our theories of social pathology and then at the dismal conditions in which children grow up in our ghettos, you would predict that all of them would be on drugs or psychological basket cases. Yet if you use criteria like gainful employment, forming partnerships and life without crime, you will find that most of those kids make it.

People who are burdened by acute misgivings about their coping capabilities suffer much distress and expend much effort in defensive action... they cannot get themselves to do things they find subjectively threatening even though they are objectively safe. They may even shun easily manageable activities because they see them as leading to more threatening events over which they will be unable to exercise adequate control.

Moral justification is a powerful disengagement mechanism. Destructive conduct is made personally and socially acceptable by portraying it in the service of moral ends. This is why most appeals against violent means usually fall on deaf ears.

People who underestimate their capabilities also bear costs, although, as already noted, these are more likely to take self-limiting rather than aversive forms. By failing to cultivate personal potentialities and constricting their activities, such persons cut themselves off from many rewarding experiences. Should they attempt tasks having evaluative significance, they create internal obstacles to effective performance by approaching them with unnerving self-doubts

Ironically, it is the talented who have high aspirations, which are possible but exceedingly difficult to realize, who are especially vulnerable to self-dissatisfaction despite notable achievements.
