OP, you're putting her on a pedestal. Doesn't help. You'll be all hot and bothered around her, which (dents your confidence when you even talk to her),because you'll be speculating the worse and thinking 'don't screw up' all the time which doesn't make you look chill.
Asking girls out usually works if you're not too bothered if you get her or not. Say there's a girl, you like her and you're interested but not too insanely crushing on her. Now this sounds a little strange but from experience and from watching people you'll be more motivated to do it if the risk isn't as high, gives you the ability to bounce back quickly from rejection and it also gives you the opportunity to know the girl better through dating without your perceptions of her and the impacts of intense crushing clouding your judgement.
(Also from that thread on bodybuilding.com don't use everything in the book.... I mean I call BS on the 'scale'. I mean... 2/10 goes to personality? REALLY?
