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.
When you are reading, someone has done a lot of work on your behalf, someone has had ideas and has then written and corrected and improved them so that they can be shared.
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.
I, personally, have found reading a continual support to writing.
