Landing an airplane is like golf: No matter how good you get, you can always be better. Nobody hits a hole-in-one every time.

For aligning with the runway, I like to put the airplane aligned with the fence/barrier/flightline just as I turn final. Then it is going ever-so-slightly away from me to the touchdown point.

If you are arriving with too much speed, don't let the nose down in your approach. Elevator controls speed. Throttle controls altitude. Bring the fuselage to LEVEL, and cut the throttle. It will come down, nice and slow. then when you're close to the runway, flare and hold it off an inch high until it touches down.
