So I've got GTD pretty much completely set up, and I've been using it fairly successfully for over a year now. I've got a good, solid next actions list that really and truly are the next physical action I need to take. I do my weekly review thoroughly and religiously. All of this has help me improve my productivity remarkably.

But...

I'm still an inveterate procrastinator! I still find myself sometimes working marathon sessions to complete tasks with deadlines that I had plenty of time to complete but avoided working on for no good reason! Can anyone share any tips or ideas for breaking the procrastination habit? Many thanks in advance.
