So, imagine that you have a very long runway in front of you. You fly the mighty 152 across the threshold with 20 flap out, right at Vfe, precisely one foot over the surface, 'cause you've got that part of low flying figured out. You've got the plane right in the groove, one foot off, right on the centerline, and you could hold it there all day long...
Your task now is the groove, keep it in that groove no matter what!
So now smoothly reduce the throttle to idle. You're going to have to pitch up as well, to compensate for the elimination of thrust. But you're going to keep the plane perfectly in that groove, it'll just be steadily slowing, and you'll be steadily increasing pitch, to compensate for the slowing airspeed.....
Just keep doing this... keep it in that groove, it's perfect!
At some point, you're going to hear the stall warning horn - IGNORE IT! (after all, where could you fall!). Just keep raising the nose as you've been doing - keep it in the groove. Soon, after the stall horn your ignoring, you're gonna feel the mains gently touch the runway - ignore that too, keep the plane in the groove the best you can! Yeah. I know that you're on the ground, but focus on keeping it in the groove.
Oh yeah, as you roll out perfectly, holding the nose wheel off, in the groove as best you can, you landed really well - bonus!
Over time, you'll find you can repeat that perfectly, it will just happen with unconscious competence, and in less runway length, but patience.... It'll come...
