The way it works for me on the bus: correct for trends, not for upsets. Chances are, if the attitude is changing, it is because the airplane is correcting. So don't fight it. If you are hand flying with the FD OFF, look at the LOC/GS direction of movement, look at your course and VS. correct for trends on the LOC/GS, try to keep course and VS constant, and move the stick as little as possible, stop trying to fight attitude changes.
If you have the FD ON, keep the needles centered, or even better, turn the AP on, because you aren't really flying anyway.
Pretty much what FIS said
