One thing which may help is using the Procrastination tape/CD. Paul Scheele once said that he, himself, uses this one a lot, and I have found that I do too, and it helps me tremendously. If there is something I want to do or have to do and just can't seem to actually do, I listen to this tape (or now, CD), and afterward, I just naturally feel the urge to do whatever it is I couldn't previously do, and I do it effortlessly. For me, that program is magic.
