Writer's block.
We're all going to get it one day. There will come a time where no matter how hard you try, you're not going to be able to come up with something to write about, something to talk about. You could be mid-script and find yourself unable to pound out the dialogue for your next scene. Maybe you have to come up with a new story idea and find yourself stuck.
Or... and I'm just tossing this out here... maybe you've got a new blog post due and can't think of anything useful to impart.
So how should you deal with writer's block? I'm a fan of not forcing it. If you can't write, just give your brain a break and do something else. For me, that usually means either catching Law & Order reruns, or diving into my Green Lantern back issues.
So how do you deal with writer's block?
