I agree with what you're saying, Neil Sperling, about re-framing your thinking and so your feelings about procrastination. "Personifying" your different behavior trends is a very humanizing as well. That makes the change process easier.
However, the simple approach I'm outlining here is more about getting from point A to point B on simple work tasks that people are in the habit of avoiding or under-performing on, independent of larger "personality issues" that may get in the way. I think this process is actually complementary to the one you describe on tasks that can still stand for a little performance improvement.
Although, this approach is also the basis of the most effective non-chemical treatment for clinical depression (see wiki on activation therapy, or the recent major "component analysis study" in cognitive behavior therapy to see what part of it works best and why).
