My landings sucked until I stopped listening to my instructor and just did what I thought I needed to do. Now, obviously, I did not disregard his instruction, but I needed to just fly the airplane and do what needed to be done. It is hard to explain but the landing is finesse. That is something that is difficult to teach. It is one reason why NAVY pilots suck at landings.
(Flame on!) Just kidding guys. There is no room for finesse on a carrier landing. You fly the numbers and plant it. If you want to qualify, that's what you do.
Anyone can land. A GREAT landing takes lots of small, fast movements in the last few seconds. (and some good luck) It is difficult to teach that. You have to trust yourself and do the movements you know you need to do. Fly the airplane until it is on the ground, like Pilotpip says. Never give up and just hope for the best. Something tells me you have had a few landings like that.
