1. Don’t start with a blank page. If an idea for any sentence has popped into your head, write it down. It doesn’t matter if it’s your first sentence, middle sentence or, closing sentence, or even a bad sentence. WRITE IT DOWN. It’ll stimulate more ideas that you can write down.
2. If you’ve come to a blank page with no idea for writing already in your head, look at the room around you. Choose 3 or 4 objects. The less connected they are, the better. WRITE THEM DOWN.
Then start writing using the words you’ve chosen. Keep writing and let your imagination take over. Don’t stop to edit out mistakes or crappy writing.
Once you’ve finished, you can go back and edit out the random words, add in sentences where needed, refine imagery or correct spelling and grammar.
NOW GO WRITE SOMETHING.
