It may too late for this in your current situation, Lostinwonderland. But what the Skeezyks would typically do is to try to plan ahead how much I would try to accomplish within the amount of time I have available. Then, when I'm done... I'm done. As a take-off on this, perhaps you could pick one of the tasks you want to accomplish & "peg" it as being the final task to be accomplished. Then when that task is completed, let yourself be done. I don't know...

it's tough... sorry I don't have better ideas.
