One thing I learned from teaching: never let a little personal dignity get in the way of enthusiasm. I have no idea what I'm talking about here, but I'm pretty sure the audience is laughing. (I mean...how could they not be?)
I'm a veterinarian who started writing and never stopped. I've published two young adult novels: Ten Cents a Dance, which was named a Top Ten Best Book for Young Adults by the American Library Association, and Tallulah Falls, which was named a 2007 Book for the Teen Age by the New York Public Library. I practice veterinary medicine part-time; the rest of the time, I'm up in my office, clacking away at the keyboard.
