Choose a room that has changing features. If you have a teen-ager living under your roof, their room is an excellent target. In the beginning of your remote viewing exercises, use only easily-verifiable targets in the present. You will be able to gauge your progress in remote viewing this way, and you will not be misled by malevolent entities. Some will be able to pick up the basics more easily than others.
All people have varying natural abilities in all endeavors, remote viewing is no different.
If you start slowly, and progress at your own, natural pace, you will be able to discern when they are present, and you will be able to shut them out. If you have trouble getting things to work, post in The Forum. If I am unavailable or unable to help, there are many other people there who are very intelligent and who will be able to help. Above all, keep trying. It will take time, but with practice URV will work for you.
