It's good to have a list TODO for some next days (at least it works for me). But not a rigorous one but more like flexible plan. You may have those days where you just write everything gibberish and it may be very demotivating. During this time I would more suggest you to read more about subject or something around it. Don't forget about breaks - they are very crucial. For example try to write something for 30 minutes, then do a break for 15-30 minutes, write for 40 mins, and over and over again slowly increasing time you spend on your work and adjusting your breaktime.
Personally when I study I love switching from physics to chemistry and then to maths. It's really effective for me instead of hanging over chemistry all the day. But I think it won't help there.
I think you should be able to do one page in one day, one and half page in second day (I meant here you should be able to increase your progress slowly day by day). You shouldn't forget about thinking about things and go to bed with them. If you are worried you won't remember them in next day - write it down. Have a notebook (or smartphone) somewhere under your bed or somewhere else.
If you play video games much, I suggest you uninstall them unless they don't distract you. All of them. Even mobile games.
If you go by bus/by tram somewhere it's a good time to think of stuff as well.
When I used to do long reports on labs sometimes contacting with other people around the world helps as well. But as I mentioned that in video games part, unless Facebook/Twitter/MV don't distract you.
And PLEASE, don't stay late hours hanging over your work. It's not effective at all. Don't forget about your bedtime, sleeping is important.
EDIT2: Forgot to mention about rewarding yourself after reaching your daily milestones. Eat something what you love, play the game for some hours which you love or do whatever makes you feel better and happier. Staying in good mod during writing helps a lot.
