Writer’s Block

What is this thing called writer’s block? It feels like a large wall in my brain, through which no words can escape. And I sit in front of this screen feeling empty. No words come forth from my fingers on the keys. No ideas spark a story. There are no ideas at all. And nothing that I read or try will cause anything but this emptiness, and this wall, which blocks all creativity. The only urge I have is to stare out the window at the leaves blowing in the wind, and to listen to the sounds of traffic in the distance. There is no energy.
