Alcohol works pretty good too.
Maybe so, but alcohol is only temporary, whereas real confidence is permanent... besides, alcohol can really work against you. And
every guy does it, that hot woman you want to approach has been approached by thousands of drunk guys. You're just another one of those boring, obnoxious dudes if you rely on alcohol.
Honestly though I'm not sure what to make of OP's post, but I appreciate his honesty. Voting down his post is kinda lame tbh. There's nothing shameful about feeling uncomfortable around hot women, in fact: we men evolved that way.
Feeling that kind of fear is completely natural. 100,000 years ago, when humans still lived in small hierarchical tribes where everybody knew each other (~60 people), men had to be very cautious in selecting a mate. Their lives literally depended on it. What if that cutie you want to pick up is the wife or daughter of the tribal leader, or the most aggressive alpha male in the tribe? He could easily kill you if he found out. Or the rest of the tribe will remember and laugh at the fact that you got rejected, etc... So the fear most guys feel during the approach is kind of an evolutionary leftover, but once you realize this it becomes much easier to conquer that fear.
However, walking up to a girl and saying "you're making me nervous" gives a wrong first impression. If you're talking to her and she asks you what's wrong it's okay to say "Just a little nervous, but I'll be alright". There's a big difference between the two, the first implies weakness and the other implies confident honesty.
Nox, look up a guy called 'David DeAngelo', he's incredible. Some of his stuff is outdated and should be taken with a grain of salt, but he shares a LOT of great info. It changed my entire reality. PM me if you're interested, I can link you up with some of his stuff. It's life-changing material really.
By the way, I'm not a fan of giving 'scores' to women, but I guess it's a good way to let others know what you're talking about. Not a fan of overpainted club girls but to each his own.
