You can't expect two stars to drop in the same field in one lifetime - P. L. Travers

Nothing I had written before Mary Poppins had anything to do with children and I have always assumed, when I thought about it at all, that she had come out of the same well of nothingness (and by nothingness, I mean no-thing-ness)

Don't you know that everybody's got a Fairyland of their own?

You do not chop off a section of your imaginative substance and make a book specifically for children, for — if you are honest — you have no idea where childhood ends and maturity begins. It is all endless and all one.
