Struggled a lot with it in private, instrument, commercial. It was only when I got to instructor that I actually had an instructor that really understood how to teach it and take it apart. Then I decided to make my weakness my strength, giving as may references as possible to students to account for varying conditions and situations. Most airplanes seem to land about the same to me now. Key is getting to the correct energy state at the correct height, then when you increase the pitch, it doesn't make you balloon, it makes you arrest the descent rate and land on the mains. The timing and exact heights/points differ between aircraft, but the concept is the same. Lots of non-descriptive "reduce the power when it 'looks good'" and "look down the runway" and having no idea of the approach path did not help.
