I play music in the background, that helps...sometimes...

I've heard that you shouldn't study/ do homework in your bedroom/ bed because your mind associates that with sleep/ relaxation so then you will fall asleep, be less productive, and focus less...I personally haven't tried this out (I still do work on my bed because I have no where else to go) but it may work for you.

Would working with a buddy help? It does for me at times.

If I'm not already stressing out putting pressure or a time limit helps me finish as long as I have a reason to finish it. For example just saying I need to finish at 830 would not make me finish at 830 I'd keep procrastinating...If I said I need to finish at 830 because I also need to shower, check my email/ regular stuff on the computer before 9 so I can watch my show that helps. Also giving yourself a reward at the end may help.

In addition to giving yourself breaks (if you choose to do that) try doing a different assignment/ project/ task after every break it may help you from getting bored. Or you may be the opposite and want to finish the task before you get a break.

Hope something helps!
