This reminds me of a saying attributed to Arthur C. Clarke: "A technology sufficiently advanced is indistinguishable from magic." For someone who didn't know what you were doing, the transformation in your productivity might seem magical.
It is interesting that you say there is nothing magical about the materials you suggested. David Allen's materials have been "magical" for me at the runway level. I mean, I never thought I could handle all my shifting responsibilites in such as effortless way. It really is great. I guess I am looking for something similarly magical for the big picture.
