If I'm listening to a lecture, I doodle. This helps me. When I'm taking a long test in class, I will make myself do 20 questions, then "reward" myself by taking a little break and drawing a doodle on the back of the test. Then another 20 questions, etc. At home, I set a timer for 15 minutes. When it goes off, it's like a reward. I made it! Then I let myself get up and walk down the hall or have a snack or put a load of laundry in the washer or whatever. If I don't need to take a little break, I don't. Then set the timer for 15 minutes and repeat. It's painful!!!

I also make little charts and check off boxes for each 15 minutes I spend studying or some other task, like cleaning off the floor and its stacks of papers in my bedroom. Checking off the boxes is like another reward. Then I can look back and see I actually spent time on this and I can't tell myself "you never do anything" because I can see from my chart I actually did do something.

It's a struggle. Hang in there.
