Three point landings are bad unless you are in a taildragger. Eventually you strike the prop...$$$$$

You might want to try focusing on the fact that at the moment of touchdown, you are still flying the airplane and you need to keep doing that until you slow to taxi speed. Don't suddenly stop flying and relax control pressure or make any sudden inputs (unless needed for gust control). Whatever you were doing the moment before touchdown, you should still be doing pretty much the same thing after touchdown.

Land one main, keep the nose straight, gradually lower the other main, then slowly lower the nose. Don't release all elevator back pressure, just enough to get the nose wheel firmly grounded. Basically you are flying in formation with the runway...once you get all the wheels planted then you can slow and transition from flight to taxi.
