FLY the aircraft to the ground.
Some great advice above.
The flare manoeuvre is not a one-shot effort.
If you turned your car into a parking slot between two other cars, you don't just wrench the steering wheel once and hope for the best? Of course you would make corrections according to the crossing/closing speed and also the achieved vehicle path, would you not?
If it looks like heading for a hang-up at 5 feet, make a goddam timely correction. Relax! Don't try and turn it into rocket science!
