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.
I don't think it helped him (Tim of WbW) either. I don't think it was even supposed to help; reading his writings, I never had the feeling he was offering a solution -- rather, he was fascinated by the phenomenon, and was doing a kind of nerdy, technical analysis of his state. One that I (and others) could resonate with.
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.
