"For me in general, one of the most important things is speed and thrust. If you get this you will do good most of the times. I guess the idea is to gain or loose altitude by throttle management... Also coming in with power is much better than gliding in, in the event you need to go around."

As he says!!

Throttle for controlling altitide - elevator for controlling speed when landing. I used to struggle with landings and was told to use this method which works for me.

Practise high up and a bit away from you so you can see what the plane is doing!!
