Nail the approach speed, and, while looking well ahead, do a gradual change of attitude into the roundout, at about 6 inches above the ground..... the roundout or flare is often too hastily done.
A few years back I was flying a Piper TriPacer into Annapolis, Maryland USA, home of the United States Naval Academy. The Piper Tripacer is not a speedy aircraft, along the motorway, the cars were overtaking us without difficulty. What upset me most was that an impatient Naval Academy aircraft cut in front of our stately final approach. (there was no ATC, traffic was self-regulating at the small local airfield.)
We had the last laugh, however. The Navy pilot did a carrier style landing in front of us, and his undercarriage gave way.
