I write about what's on my mind. That can be headlines, what preparations I'm working on, an experience the day before... could be anything that directly impacts my life or thinking.
I've always been motivated by challenges, and taking a topic from news headline to fictional story is often a difficult task. I wake up wanting to get to the keyboard, my head swimming with ideas, scenes, and characters. I feel that if I'm passionate about the subject, it will show through to my readers.
