Free writing to me is equivalent to playing. A freewrite doesn’t have to make sense, it is just to be. There over 170,000 words in the (American) English language and the best work comes from stretching language to places where your imagination sees fit!
A freewrite can serve as a map, as background, or the precursor to the story you may write later.
Make time to play.
Make time to write.
You deserve it–and your work will be better for it.
