sabreuse touches on a good point. When you find that your trusted system is as trustworthy as a dockworker on slip in Shanghai, then you need to ask some WHY questions. There's no use collapsing into the old faithful standbys of "I'm such a screw-up," though that may be the case. There's a lot to learn from the stubborn, immovable tasks on your to-do list.

Sometimes it's just a matter of rewriting the action to the appropriate audience as sabreuse says. For instance, I have "make a list of networking opportunities." But why haven't I started about this. As I think about it, I don't want to create a big fat list of people I'm never going to call in a million years. Such a list would sit on my desk and mock me for not having a real career or any real contacts in the industry. Maybe I should rewrite and say "make a list of people who would be fun to talk with."

You get the point.
