I find it difficult to do either one of them for a long period of time. When I get on my computer, there's far too many distractions. I'll be in the middle of writing something and then I'll want to look something up. So Google takes me away and three hours later I finally get back to writing. But when I try to write with paper and pencil, I find myself getting lazy far too often and too soon. What is everyone's preference for writing? What keeps you motivated on the story when you're on the computer?
