Reading is very creative - it's not just a passive thing. I write a story; it goes out into the world; somebody reads it and, by reading it, completes it.
By the time ordinary life asserted itself once more, I would feel I had already lived for a while in some other lifetime, that I had even taken over someone else's life.
My theory is that I decided to be a writer when I was about seven, but of course it is not as simple as that. Like most writers, I had to work at other things to earn a living and wrote mainly in the evenings, often very late at night, for many years.
Being a librarian certainly helped me with my writing because it made me even more of a reader, and I was always an enthusiastic reader. Writing and reading seem to me to be different aspects of a single imaginative act.
It is a good idea to know which publishers publish which stories. For example, there is no sense in sending a picture book text to a publisher who does not publish picture books.
