Remembering the Planning, Forgetting the Gotten

So often I work with detailed and fairly fast-moving plans involving inter-connected pieces. For example, I need to do A which requires B and C and C requires D and E to complete, and now A has been set aside, and now I need to do X Y Z....Meanwhile, I am hanging onto A in my memory, although it was never done, I am remembering my Plan or intention. Soon enough, that "memory" becomes what I remember. At numerous points, then, I can actually "remember" A, although I never did it. Scarey. Meanwhile, my memory of what actually took place, what actually happened while I was making the over-run Plans, starts dimming. Memories fade quite rapidly as new details and observations take up attention. What I actually "got" out of the whole layered process insofar as it is either unintended or simply superceded, then fades. My work is completely over-run: Even I do not recognize the results of what I do.
