Hey! If you don't have an idea... then why don't you write about that? And use lots of juicy metaphores and analogies.
PS... here's lovely picture of me not having any ideas at my desk. Maybe I should clean it instead? Nah!
I need an idea. The distance from point A to Z is empty. It is a void so vast that it weighs more than a universe. A million seeds sprout and grow in the blink of an eye and produce a billion trees which produce a trillion seeds which will fall and sprout... and... and... Which path do I travel? Which fruit do I pick? Do my dendrites and neurons fire randomly or is there method to my madness? Will there be cohesion in my offerings or will they just go up in smoke? There is an even potential for success and failure as new suns and planets are born every second and then destroyed just as fast as comets take a glance and continue passing on by. They've been here before and the view is the same. My fingers wait upon the keyboard yet there are still pockets of air between them that contain hundreds of thousands of molecules. The idea doesn't care one way or the other because it's still a sonic ride no matter which way it travels. Besides... it is totally dependent on me as it floats across the abyss of my mind... between my nose and the computer screen... which is about a foot and a half away. Or... using other means of measuring... about a zillion miles apart. How much dark and distance is enough to smother an idea? How far can a spark be seen? How bright is inspiration?
