ex)Most people believe that praise builds up children's confidence and makes them feel secure...When parents tell a child, "You're such a good boy, he may not be able to accept it because his own picture of himself is quite different. In his own eyes, he cannot be "good" when only recently he wished that his mother would disappear or that his brother would spend next weekend in the hospital...
You're right, in this context (although the term 'time-wise' strikes me as odd here).
