As of today, I'm at 42 landings, 10 to a full stop. Quite a number of those were really shaky, and one early attempt came very close to a ground loop. It was probably 25-30 before I had the confidence to really believe I was going to put the plane down every single time without bending it, and it definitely takes time and practice to build consistency.
I am now confident that I can land the plane in reasonable conditions, but I still need a lot more practice. After 7 successive really good landings at the large field (KEFD), my final landing last night at KLVJ was a mess. I went around twice before finally getting it down properly. To be fair, it was really dark with gusting random winds, on a narrow little non-towered strip with "adequate" lights.
What has helped me is to think of using the rudder only to keep the nose pointed straight down the runway, and the yoke for everything else. My CFI prefers crabbing it in then straightening when you hit ground effect, but mentally I'm more comfortable separating the controls into yaw and pitch/roll.
Have you asked your CFI what isn't working?
