You've really got to buy into the idea that women are NOT scarce! Women want to meet men just as much as men want to meet women. We have different immediate intentions, which is why a male and female connecting right off the bat is harder, but we do want to meet men. It's never going to be completely obvious that women are not scarce, because that is not the way day to day life works, but we are not scarce.
I used to think men were scarce. Hindsight has me realizing that I wasnt making myself open enough to men, that I wasnt taking advantages of situations, like I should have. The men were there, I just didn't realize it.
The women are there and you will find them. Believe that so you dont waste your time on ones who are clearly not high interest. Women are not scarce. Make that your mantra so that when a chick isn't interested you can feel VERY confident moving on.
