Sometimes that point exists in a region of concepts that isn't touched by anyone directly, so you have no clue what its exact location is, hence you can't concentrate your energy on it.
What you can do, however is identify the conceptually closest and well understood points. These points may end up being in vastly different fields, each requiring vastly different ways of thinking and/or computational paradigms.
_IF_ you're resourceful enough to focus your attention on all of these neighboring points "virtually" at once, then you have a chance to interpolate the position the original concept and finally concentrate on it.
It's never the concept that's hard. It's the execution.
And if your energy is spent on a hundred different tasks, it's gonna take you that much longer to boil that pot of water.
This seems extremely straightforward and intuitive. Surely we do not need Einstin here to prove it for us.
