Two goals for my research paper

One main goal is to keep my topic on point and very specific.  I tend to loose focus or talk about to many things at once making my paper lack in flow and hard to follow.  My first paper I felt was also very weak in structure and was not my best piece of writing and I feel this has a good possibility to be a very well rounded paper.  I would also like to have a better vocabulary and an actual work cite page. I would also like to achieve an A for this assignment and just enjoy it.  My first paper had many grammatical errors and I would really like to reduce my waste of sentences.
