TailDraggin, you got some good advise from the above posts. I would like to add one thing that gave me fits, and still does at times. Don't concentrate so hard on the plane that you loose focus of its surroundings. Over concentrating can cause great problems with depth perception, or at least it did for me and I found it would cause me to land either in the tall grass just before the field or just off the far side of the runway.
Now I purposely shift my focus for just an instant to the end of the field, etc. if at a new location just to make sure. No problems now where I normally fly at.
