The "to be perfect" hidden agenda never made sense to me. To me it seems more like a combination of Si creative and Ni PoLR. You can't foresee what'll happen, but if you focus on the task at hand and do a really excellent job, it'll have to work out okay. The cream rises to the top and so on.
I would think a Ne hidden agenda would be wanting to believe yourself one capable of thinking outside the box, being original/inventive, coming up with brilliant solutions, etc.
