I think the best way is to just do it. Fail firs few sets and fail them badly and how do you know that you've fallen them badly? When you approach a girl with 30 people around and you embarrass yourself so much, that she tells you to fuck off and when you look up all those old laides around are nodding their head and saying, ''oh young man, why did you do that.''

(That's really EXTREME example)
After you do that so much, that when you fail BADLY and you just don't care anymore, you can say for damn sure, that you got over every and any social discomfort/social anxiety/AA/careing what people think of you/not being alpha/...
Now don't get me wrong I'm not saying go around to a crowded place and insult girls just for you having fun. No when you do approach badly, and really everybody are looking in to you, look back at everyone, hold that eye contact and trust me no one'll come up to you and arrested you because you fucked up the worst thing that can happen is laughter for them and for YOU, cause if nothing else you tried and you've learned something
