Amateur learner and a Mature learner

After I read Arthus Erea I thought something. From what I know from his article, I think that it is important that a student is a amateur learner. Teacher in the school make you cram things into your head and try to tell you that no good grade = no good job = no $$$. Well, I believe that the world is simlar as this. Although, the world didn't tell you that no good grade =no good job =no $$$, it showed a attitude and personality of doing things. The information no good grade = no good job gave from teacher is only a edge of a big image. The picture was because of no good attitude of learning and no good grade so have no college. If you don't have a good college, why a business want you?
