My writers group met last night, not to talk about our writing, not to throw around ideas, not to critique first drafts or short stories. We met to have dinner, take a breath, relax and just enjoy each other's company.
In anything you do, you need breaks.
I think with writing, because usually it's a solitary thing, taking a break means going out and enjoying time with friends. See a movie, try a new restaurant. Have coffee. Laugh a lot.
Give yourself that much needed mental break, even when your fingers are itching to get on that keyboard.
What do you do to take a break from writing?
