What did you want to be when you grew up? By the time I was seven years old, I knew I wanted to be a writer. Other jobs appealed to me from time to time - veterinary assistant, actor, teacher - but I always returned to my love of writing. I don't know exactly what it is about me that made me into a writer - imagination, persistence, certain life events - but those things have certainly added to the mix that is me.
