Sorry it's been so long. I'll get back to normal posting soon.
-Owner's Don't Knock
Brainstorm words or images about your topic. Don't stop to evaluate their worth. Keep writing down ideas. When you can't think of another word, wait a while. Often the most powerful idea will surface after you have cleared all the less valuable ideas out of the way.
Write a page or two with your eyes shut. It doesn't matter if you can't read what you've written. You are giving your mind permission to make "mistakes" and just get on with it.
Write with music in the background. Experiment to find the style that you like. I prefer baroque or classical music. One of my writing teachers needed country and western.
Give yourself permission to be emotional. If your writing begins to move you, experience the full emotion. Before your writing changes others it will change you.
