Just keep trying to avoid having the nosewheel touching the ground until the mainwheel is down.
When you feel the runway getting close bring the end of the runway into your scan which will allow you to realise how low or high you are. Then hold an attitude that will get the main gear down by adding back pressure.
If you want to slow the process down and you have a nice long runway land with a litttle more power.
Keep practicing and it will come.
