The French novelist Sidonie-Gabrielle Colette used her French bulldog, Souci, to procrastinate writing. She would pluck fleas from Souci’s back and hunt for them in her fur until the grooming ritual prepared her to move on to other procrastination techniques like cuddling with Souci and swatting flies. Only then would Colette begin to work.
Graham Greene needed a sign from above to begin working on a piece. Obsessed with numbers, the English playwright and novelist needed to see a certain combination of numbers by accident in order to write a single word. He would spend long periods of time by the side of the road looking at license plates and waiting for the hallowed number to appear.
