Have you tried doing "morning pages"? from Julia Cameron's book: The Artist's Way?
I have tried and failed several times.
My notebook is small - just 3.5 x 4.5 inches - and instead of three pages I do just one.
And instead of free write - I do a free collage.
But, as Julia promised us, it's nearly always a surprise at what comes out.
It's that sweet pearl of thought that falls miraculously out of the swirl.
Something to go on for the rest of the day.
