I'm a big fan of Jane Austen too. We read Pride and Prejudice in my English AP class in high school and everyone else thought I was weird because I finished reading it WAY before we had to and then I reread it several more times before anyone else had even finished it. I love that book especially but I love the others too.
Reading literature such as that is doing a lot to help fashion you into an expressive writer and speaker. Not to mention the enjoyment it brings.
