People ask me if I ever thought of writing a children's book. I say 'If I had a serious brain injury I might well write a children's book' but otherwise the idea of being conscious of who you're directing the story to is anathema to me because in my view fiction is freedom and any restraints on that are intolerable.
And by the way everything in life is writable about if you have the outgoing guts to do it and the imagination to improvise. The worst enemy to creativity is self-doubt.
