@HF No, we didn't plan every story. But, you will notice that the ones we planned are close to finishing, like the Wikia Catastrophe. And we're not phreaking over it, we're finishing it. Before New Year.

Nevertheless, your story will not be finished and you will get writer's block if you don't have a plan. An alternative is to make a short story.
