As far as my nonfiction writing experience, last semester I took Advanced Expository Writing, which was all nonfiction. I enjoyed it a lot, perhaps because I found it easier to draw from what I've experienced than to create a world completely from scratch. Or maybe I am just self involved enough to want to write about myself all the time so everyone can know how great I am! That usually tends to backfire when I realize that my own life is something that even I don't find particularly newsworthy, and from what I can tell, people always find their own life much more interesting than anyone else finds that person’s life to be. But I guess that’s what it’s about: trying to find a way to tell the world all the truths you've come to understand and question and invent in a way that does make people care.
