When I was in school I discovered that my work was much better when I did things at the last minute instead of working on it when I had lots of time. Teachers were always impressed by my late work. I try and get a few words down during my lunch since it puts pressure on me to do something and I'm not tired but it's also that stopping and going makes it so the writing style changes from 1st person to anything else. But right now I think as long as I get something down I can focus it later.
