"For 20 years my paycheck was coming from my veterinary degree and my writing was my hobby, and I thought it would be really cool to flip that around. Veterinary medicine is much harder. It's a 14-, 16-, 18-hour-a-day job. I owned my own practice, had 24 employees. I couldn't get away, that was the biggest thing. In the 10 years I ran my own practice, I had three weeks of vacation total. I started writing during my lunch hour at the clinic—dogs barking, cats meowing—so now I can write anywhere."
