This is why I don't use routines at all. You need natural game man. Check out this vid.

Rsd stuff is golden.
As far as your friends cock blocking you. try the natural game right in front of them. Either they will see that you are pulling no routines and their defenses will be lowered... or they will accuse you of pulling game. That's the beauty of natural game. It can only work in your favor if you were speaking to her normally and they try to cock block you. She will get the impression that you get girls just by saying hi. Total social proof. My advice is. When they try and cock block you, laugh in a fun confident way, as though you were caught pulling a practical joke. Then look at her and say something that is congruent to your REAL personality, that twists it into a false dis-qualifier. If it makes her laugh then you are golden. If it were me I'd say "Sorry, guess you miss out". Then I'd ignore her to no end and mac other girls. lol. idk, like I said, I don't use routines. I walk up to women and say. "Hi"
Anyway, friends of friends are easy. And what Derek said.. practice on other girls. Embarass yourself on purpose if need be. Walk up to strange women and tell them you are gay. What ever it takes to kill this fear. I am NOT afraid of women at all. Maybe afraid of messing up sometimes so that can screw me. But otherwise there is nothing that I couldn't say to a woman for shits and giggle.
