American 1 to 10 system. It is based purely on superficial elements. It's pretty easy to identify where you stand. The whole thing is relative, but I would suggest going for 1 point above if you have money, or can offer some other thing in large amounts to women that they seem to enjoy. The people you get crushes on are at least two points above you. They are like ivy league schools in my experience, either you are already in or you never will be. Go ahead and give it your all, but know that it is a longshot. Achieving a relationship happens when two people find someone within their point range (-+1). This just how humans work.
Now if you are lucky enough to find a geek, I really hope you will consider adding a +1 or +2 depending on their compatibility with the niche items of geekdom you subscribe to. Everyone thinks they are a 6. I am a 5. I accept that and only date 4-6.
If only I could find a Doctor Who, Battlestar Galactica, PC, TBS, RTS, SoaSE, Buffy, existentialist, cynic with a cool detachment from humanity that hates the daylight as much as I do, I could end my search. Maybe I need to get off the dating websites and start looking at mental hospital records.
Everyone is different I guess. Damn.
