It wasn't until I lowered my standards and said I was okay with average to below average looking women that I finally met a couple women.
I decided I want a woman to talk to and maybe be intimately involved with a woman, and the best way to go about that was to go after a woman I have a chance with. Online dating does not have the greatest women in looks, and when those certain hot women are on there, good luck getting a response, much less a date. And I say that to any guy out there. I speak of online dating because that's what I used and I think it's a decent way for shy guys to meet women.
I think in order to get attractive women, which I believe are only about 15% of the women (just my belief, don't kill me), a guy must have high social status, above average looks, and a lot of social confidence. The other problem is attractive women are the most sought after women for an obvious reason (such as they are the most appealing). If an attractive woman isn't in a relationship, she's looking for that next alpha male anyway.
It depends on who you are. If you don't fit that alpha male profile, I'd highly advise lowering your standards. The biggest field of women are average looking women, so why not play to that bigger field and improve your odds. Don't forget, the most important part of the relationship is the social connection. At least it is for most people, unless you are humping every second of the day and night.
It depends on what want, too. If you are looking for marriage, then obviously you don't want to lower your standards much at all. If you are just looking for a relationship, though, then lowering your standards can be beneficial to the people who had high standards and decided to lower them.
