My biggest source of procrastination is the fear of making a change that can't be undone. I find this particularly challenging on projects around the house like putting in a new door, and having the door ready to be hung on and knowing if I screw up the hings placement I need to get a new door. Blam! I procrastinate the crap out of taking the irreversible step of routering in the hinge mounts. I have to sit down and give myself permission to buy a new door if I screw up, and even then it's painful to move forward.
I never really thought of it as a judgmental problem (self worth related) so much as a sort of efficiency problem (hate to have wasted all that resource (time, money, whatever)). One of the weird things about quitting World of Warcraft was that I played hours on that game, so I could pretty much do anything and it would be less wasteful of my time than that. So for a while that was a great crutch, "We'll hey, I didn't get much done but if I had been playing WoW I wouldn't have gotten anything done."
The fear of screwing it up, coupled with the knowledge that I really am not good at things like carpentry, and rounded out with a lack of funds to hire others, have played havoc on my ability to finish my basement or my back yard.
Ironically, I have managed to keep my washer and dryer going for 16 years. But that's all thanks to the Internet. :)
