Plot School on the Porch from Jeannine Atkins blog.
I would say, myself, that the hard part is remembering everything I've studied and have been trying to train myself to do so that I can then do it. Oh, my gosh...I shouldn't have used "remembering" and "training" in the same sentence. It reminds me of how badly my martial arts class went Wednesday night, which is kind of related in terms of having to remember things and then apply them...and apply them well, not just approximate correct behavior. There is a writing/martial arts metaphor in there somewhere.
