Essays / Struggling with my virtue ethics paper [6]

I'm not sure if this is the right place to post for help, but here goes.

I am a terrible writer, and an even worse ethicist. That being said, my ethics professor has assigned a paper where I have to choose a cardinal virtue from Thomas Aquinas's writings and then define the virtue in my own words. I have to discuss the communities of which I am involved in, and devise a strategy to introduce this virtue into the community, explaining how I would go about it, and what I predict the results will be. I have already compiled most of the body and conclusion of the paper, my problem is writing a thesis statement. This professor is extremely picky about the structure and wording of the thesis and conclusion paragraph. Any help or advice on how to best go about writing the thesis would be much appreciated. If I need to post anything from my paper so that you can get a better advise me on the thesis, please reply and I will promptly have it posted. Thanks in advance.
