Hi all! I found a great new (to me) resource. It is called the Pomodoro Technique.
This explains it quickly and has links to more resources: http://www.makeuseof.com/tag/3-free-pomodoro-productivity-apps/
Basically, you break down tasks then do them in 25 minute segments. After each 25 minutes, you get a 5 minute break. I am still learning but I used it yesterday and it was really helpful to me!
There are free desktop timers online: http://code.google.com/p/pomodairo/
