writing then vs. writing now

when I first came into Preston's class I didn't care about writing. I would write an essay just to get credit for. I wouldn't actually think about the prompt I would do as little as possible just for the grade. But now I actually love writing. I turned in a paper today and Preston said its the best thing I've written so far. The only thing that is different from my writing then and now is that now I know how to look at a prompt and dissect it. Now I actually know what to write about and now that I do it makes writing fun for me for the first time in my life.
