problems facing me

I think that my biggest problem is lack of concentration and procrastination. I constantly find myself trying to do something and then struggle to finish whatever it is was I was initially trying to finish. I hate sitting down for five hours and getting an hour's worth of work done. I seem to end up staying up late the night before a big paper writing it although i've already put in countless hours sitting in front of my computer trying to REALLY get into it. I really need to learn how to spread out the time I spend on my paper and really work on it when I do it.
