For the past two weeks, I've written about 20,000 words of my novel. It was pretty easy, I had the plot laid out and knew where I was going.
Until last Monday.
That was when I hit a bump on the road. It was no ordinary bump. It was about the size of...the earth. The only way to get around it was to go all the way back to the beginning and restart.
Some people call it Writer's Block. I call it the Cow in a Ventilation Duct. Because it's a lot funnier than just saying "I have writer's block." Instead, you can say, "I have a cow in my ventilation duct."
Some people will tell you that there's no such thing as a cow in a ventilation duct. Well, yes, there is no such thing as that...until you see it for yourself.
You know the cow needs to be remooved. So you pull on its tail and tug. After three hours of tugging, the cow is now one complete centimeter further out of the duct than it was three hours ago.
There's no easy way to remoove the cow. The only other solution is to just destroy the duct. Of course, that will defeat the purpose of writing and will just give you even more work.
So here I am, staring at this cow who's mooing hysterically at me, wanting to be remooved. I'm tired. I don't want to. But I have to sooner or later or this book will never come out.

Yeah, that's all I gotta say.
