So, I started a blog post to answer that question last week. It was awful. I couldn't figure out why I wanted to write light-hearted women's fiction (aka chick-lit). I could think of really good, mature reasons to write a memoir or a children's book, but none for women's fiction. All I could come up with was: to see what the cover would look like.
I was ready to just give it all up. And I did for a few days. I just stopped working on stuff. But, tonight, I think I've answered my question.
I am doing this because I love to read light-hearted women's fiction. Think Sophie Kinsella and Emily Giffin and Lauren Weisenberger. These books help me escape. And laugh. They make me want to skip down the street while wearing a flowy pink dress and stilettos. To get a mani/pedi. To kiss my husband.
So, I am doing this because I want other women (or men) to feel this way, too, when they are reading something I wrote. To just have a little fun, darn it. Life doesn't need to be so serious. Books don't either. That's what I say, anyway.
