School success is not predicted by a child's fund of facts or a precocious ability to read as much as by emotional and social measures; being self-assured and interested: knowing what kind of behavior is expected and how to rein in the impulse to misbehave; being able to wait, to follow directions, and to turn to teachers for help; and expressing needs while getting along with other children.
Daniel GolemanPeople who are optimistic see a failure as due to something that can be changed so that they can succeed next time around, while pessimists take the blame for the failure, ascribing it to some characteristic they are helpless to change.
