“Keep your eye on the ball!” (Note, it is the trying to keep your eye on the ball that seems to provide the benefit. If you study the actual motion of the eyes the last instants of motion basically don’t get tracked anyway.)
Perhaps the demonstration used in martial arts classes where you put your extended arm on someone else’s shoulder, elbow upward, and try to lock it in place while they pull downward on it; then you experience much more success by trying to point at the wall behind them?
But that’s longer and more awkward, both verbally and conceptually; and could be less widespread than trying to carry a full cup.
Can you suggest a better example of replacing an ultimate goal by a proximate one?
