My 12 year old son introduced me to a hilarious series of cartoons on YouTube. It's all about providing alternative endings to popular films. (If you search 'how it should have ended' on YouTube, they'll come up.) Some of them, such as the proposed alternative ending to Braveheart, are just surreal. But others give much food for thought to writers.

It's very simple: our subconscious (which is our friend and wants to help us) believes that writing is dangerous, and so it wants to stop us doing it. And because our subconscious, as the root of our creativity, is where our stories come from, it's in a very good position to stop us writing!
