Dealing with Writer’s Block

“When you get writer’s block, if you will go back in your story to what you wrote the day before and check your work very carefully, you’ll find that you wrote something that your subconscious mind recognizes as being utter baloney, a lie. So you have to find out where you went astray, and start writing from that point forward.”
I really think that this needs to be expanded upon, for those who feel stuck.
