Sunflower seeds are my latest writing trick. I go down into the kitchen and eat them (which is a whole process, to cleverly shuck them between your teeth and extract the kernel with your tongue and spit the empty husk out), and because it takes forever to eat them, I think, and I come up with perfect solutions for my scenes, and I rush back upstairs and I write. Then I come down again and eat more sunflower seeds.
Half a scene written today! Thanks to the seeds.
