I just saw this very cool post which seems to make a very accurate observation.

Especially for a man like me with less than good history with women. Knowing which women are interested can help immensely. The initial success with these women can snowball into much bigger success in the future.

However we all have to start somewhere.

What happens if I identify most of the IOIs and even in real life scenarios for friends but very rarely when it comes to women checking me out?

Any resources on that? Any refreshers as my perception seems skewed?
