I've written several short stories, some flash fiction, some longer, and I generally find them fairly easy to go about. I never find myself wondering what sort of a sentence to write. Then suddenly, I try to write a novel, and every sentence is grueling to write. And I'm not necessarily talking plot. I'm talking just about figuring out words. What do say, and what not to say. Of course there is a difference between a short story and a novel, but can anyone explain why my mind suddenly blanks when I'm writing a bigger piece? I think it may be because I'm not focusing on a single small event, and so my mind it wandering, but I really don't know, and it's driving me crazy. It could probably take me 4 hours to write a few paragraphs if I have the mindset of it being part of a novel, and probably get 6 pages written during that time if I told myself it was for a short story. What gives?
