The problem is that I live in a small town and never see more than 2 women worth approaching in a day.
Then that probably not going to work since they always say the first few approaches are warm-ups. If you are starting each day with what should have been a warm-ups, then when you approach that first hot girl your nerves will hit the roof then you don't have a chance.
You need to practice your approaches with women you are not attracted to first (ie just approach an old or married other type of women you don't like and start a convo with them and eject), at least at first as a warm-up and maybe for the first while or so. Your approach when your ego is not on the line and you are not feeling outcome dependent will be different then when it is an it's a single young attractive woman when it is.
No matter what advice anyone gives you, your tonality, delivery, way you are coming across will always reek of desperation and low value because you are too nervous. You need to relax and be able to think on your feet more than think of the right words to say.
