Well, you can't edit a blank page. Believe me, I've tried.
But you can make it into a paper aeroplane. Then, whilst the more spatially aware part of your brain is ordering the folds and creases, the deeper subconscious may well be producing something of literary merit.
But if your room is littered with a ream's worth of paper aeroplanes then it's probably not working for
you.
