Re: A little advice with one really pretty girl
To boost your confidence, you need to practice on ugly/average girls for a short period (one week) in order to get some experience/practice. DO IT ASAP!!
Approach them to knock your anxiety. 10-20 girls and you'll see improvements then you can move on ( you really seem to like her and you don't want to screw up, I've been there and this is the only method, However, there are things out of your control, so there are always chances that she rejects you and it might not be your fault, some thing you need to man up about)
To be successful in this area of life, we have to maximize our efficiency in every step, which concludes that if you're only playing the number game without any techniques, you're failure is far more probable than if the game was played more effectively.
