I went onto the healthful chat .com or something in the ADHD section and you meet people there where you can do "tasking" which is doing a task that you need to get done with someone else or more people in a set amount of time. It is REALLY effective and I recommend it for motivation.

Today was the second time I ever fell asleep in class because my class was reading a novel and it doesn't help with motivation when no one else is paying attention either..
