English is complicated

So last week in my English class we had to turn in our third/ final draft of our essay.  I thought my first draft was written pretty well so I barely made any new changes to the second draft when I turned it in.  However, when I got the second draft back from Mr. Hall, he made me realize that it wasn’t as great as I thought it was. From the comments that he had written on the side of my essay, he showed me that I wasn’t focusing on the main topic that the author was talking about in his article.  After working on the essay for five or six hours, I thought again it was pretty good. Sadly, on Monday I came to his office so he could overlook my essay and I didn’t hear that many goods things that I thought I would be hearing. He thought the introduction was still not connecting to what the author was mainly talking about.  The weird thing was that my conclusion was written pretty well for connecting to the issues the author was talking about. So once again I spent a few hours working on the introduction and fixing other issues. I came back to his office on Wednesday and I finally got somewhat good news about how I was connecting the main topic about what the author was talking about but he said that I need to be clear and concise. I spent another hour on Thursday and I hope Mr. Hall sees how much time I spent on this essay because I felt like this is the most time I have ever spent on his essay.  After going into office each time and hearing how I had so many things I needed to fix made me so frustrated. Sometimes I wanted to quit and just turn in what I had but I need to get an A in this class so that I will be able to get a 3.5 GPA for this semester.
