Your success in this course involves both effort and commitment. If you wanted to participate in a sport, you would practice that sport conscientiously. In any sport, there are rules you must follow and a language you must understand and use if you wish to become a competent participant in the arena, on the court, or in the field. Likewise, in academic writing there are rules you must follow and a language you must understand and use if you wish to become a competent particpant in the university. Unfortunately, even if you practice as conscientiously as possible, even if you follow all of the rules and use the language, you may still only achieve an average level of competence.
Innate talent plays a role in writing just as it does in sporting competitions.
You might live on a basketball court, practicing twenty hours a day, and you still would not necessarily play basketball like Michael Jordan. Furthermore, I don't believe that most of you would expect to play that well, or even nearly that well. This does not discourage you nor does it detract from your pleasure in the game. That does not make sense, does not compute. It DOES NOT mean that you are a loser, a failure, or that you cannot write.
