(78) For instance, when in a new situation, an intelligent person thinks about the situation, not about himself or what might happen to him. He tries to find out all he can, and then he acts immediately and tries to do something about it: He probably isn't sure how it will all work out, but at least he tries. And, if he can't make things work out right, he doesn't feel ashamed that he failed; he just tries to learn from his mistakes. An intelligent person, even if he is very young, has a special outlook on life, a special feeling about life, and knows how he fits into it.
If you took at children, you'll see great difference between what we call "bright" children and "not-bright" children. They are actually two different kinds of people, not just the same kind with different amount of intelligence. For example, the bright child really wants to find out about life—he tries to get in touch with everything around him. (79) But, the unintelligent child keeps more to himself and his own dream-world; he seems to have a wall between him and life in general.
