The best advise I can give, already has been posted by two pilots:

Scott Harris: "Practice, Practice, Practice"

Joey Saprano: "Bad approach, go around"

I always do a gear pass and set up for landing with 2 minutes left on my timer, so if my approach doesnt "Feel Right" I go around and start over. I have over 600 flights on TamJet Superhornets, and I still need to do a go around about once every 10 flights. At California Jets, it took me 3 attempts to land Lou's Big Yellow twin F-18 because I just wasnt feeling the groove. The point Im trying to make is that most bad landings I have seen (many of them mine) have been from bad pattern work that gets even worse when you decide it will all get fixed if you just land the plane.
Good Luck,
Dave
