While I've spent a lot of time reading everything he's written, I never felt that any of it helped me overcome my procrastination. It was just recognition and a shallow, fleeting satisfaction in that recognition.
What actually helped me was framing the issue in a somewhat buddhist manner. I purchased his Panic Monster and the Monkey, sat them on my desk, and tried to look at them (and thus at my procrastination) with kindness and acceptance.
FWIW, my procrastination hasn't gone away (here I am, on HN); but it shrunk, and it stopped being such a big problem for me.
