Just write

Start raw writing
From the soles of your feet, not the heart
For the love of god ease off your delete button and unclick your undo
Close the thesaurus and the dictionary and the coffeepot lid
Let your mind go feral
If you are dark and cobwebs and fresh lacquer on coffins
Tell me how hearts taste when pickled and sliced
If you crystals and tarot and women with big grey curls
Write about how the waning of the moon reminds you of mortality
If you are swirled marble and ionic columns and outdoor dining
Praise Apollo until Greek choirs come down from the heavens 
Rhyme or meter or tempo yourself with metronomes or meteors falling
Swallow lozenges so the words bubble up smooth and easy
All you have to do is begin
