Writer's block is/are a dirty words. I use many things to help staring endlessly at a meaning cursor. Walking away is my first choice. Sometimes for a whole day or more. Next, would be looking a Facebook, Pinterest, twitter and Instagram. Anything to put off the whiteness of the page. If you are under a deadline, I do something repetitive, like walking, running or knitting. At some point the words come, I try not to put too much pressure on myself.
