Your fingers seem asleep, your mind is unfocused. What is going on? Not much it seems. So what to do about this? Close your eyes. Ok. Then write any word that comes to mind but write it down on your computer, on paper, on your hand, on a 3x5 card, on the wall (well...maybe not the wall). Write the word without thinking about it. Now write the second word. It does NOT have to follow the other word consecutively. Just write it down and then a third random word etc. No thinking allowed here.
Keep going until you stop. Then take the first ten words and use them in a paragraph. Then the second ten words in the next paragraph. Write fast. Do NOT ponder your choices.
Pretty soon: magic happens - you are writing. Your brain will help you make sense of all of this and you will find ways back to the logic of where you were stuck in your previous writing. But allow yourself this freewrite...it is letting all those words puddled in your brain to spill out. Bravo for you. You did it!
