I play games! Really! I just need some time away before continuing. Sometimes I just need a few minutes, but other times I may need an hour or so. If games don't help I might listen to music or take a quick nap. Taking your mind off of it for a while will allow you to have fresh ideas when you come back. Sometimes, what you did to take your mind off writing could influence or give you new ideas for where to go when you're stuck!
