Not sure why you're placing so much value on looks. 'Looking' high value depends more on body language and disposition, not your perceived beauty.
As far as your high standards which for some reason you feel you deserve, if you're talking to all 8's and above and none of them are interested in you, you go home empty handed. If you're talking to all 7's and below and decide you're not into them, you go home empty handed. But at least you get more practice talking to the 7's and below, and actually have a shot at getting with them considering your limited skill set.
You can become selective when you've reached the amount of incoming that facilitates that need. If you're asking us for advice, you're not even close to that point.
Guys who say they are extremely picky, only talk to 10's, blah blah blah, are spending hours a night in the fapcave or are virgins. Take your pick.
