I'm an even worse procrastinator and what is helping me the most is Beeminder: You define a goal and pay exponentially increasing sums of money if you fail.

For it to work you need to dislike losing money, be honest about your goal progress and rerail if you derail (although they now have an automatic rerailing feature). Getting some pleasure from the goal progress and statistics is important too.

I'd start with something like "study 1 pomodoro/day of $course" and slowly increase it. Maybe also add a time requirement ("by 2 pm").

The fact that I have to rely on something like Beeminder to get things done can be a little hard to accept. I'm essentially the same procrastinator, I'm just forced now to do things. I have yet to find a way to fundamentally change myself but if there is, then a structured life surely is a better starting point than being depressed because you've procrastinated your life to shambles. I also have some hope that the habits formed with Beeminder will have some deeper self-discipline changes in the long run.

Apart from the slightly mentioned Pomodoro Technique, Anki also helps me.
