Unfortunately, the pain that you feel will not go away, no matter how long you've been a pua. I've been doing it for ten years and I still feel the pain of a hot knife in my heart when a girl insults me. What can even be worse is when you're in a bar and the girl and her friends start throwing insults. That's when you go home and stare at the ceiling until six in the morning. Those kinds of nights can haunt you for weeks.

The good news is that when you've been a pua for an extended time period you will learn how to deal with the situation differently. Sometimes pain is our best teacher. Insults are good at chiseling our ego's away, and a big ego is not a good thing to have when you are a pua. The less your ego is, the more women you'll bed.

I have learned to take insults and then feed them back with kindness. I'll say something like, "Oh, you're having a bad day. I'm very sorry for that. I hope your day gets better." I'll say this in a genuine way, as if I'm a psychologist of some sort who just realized that her day is going shitty. Instead of acting sad or mad, I act as if the problem isn't mine, but is in fact hers, which it is. By acting concerned about "her" problem, I don't come off as confrontational, rather I come off as a genuinely concerned person. She, after all, is the one with the problem, and that problem is really uncool. I've also used these tactics on guys who want to fight me, or even the rude cashier at the store. He is the bad guy, you are the good guy. He has stepped out of bounds of what is considered socially acceptable behavior, and you are the good guy trying to help him out of his deranged way of thinking.
Just yesterday I had a cashier at a store try to start a heated argument with me. I just looked at him and said, "You're a good man, have a great day." The tone of voice that I used was that of "I am the smart one, and you are the chump. Because of my superior kindness, I just blessed you with a "have a nice day" even though you don't deserve it." I said it with concern in my voice, in such a way where he is now holding the bad guy hot potato and can't get rid of it because I am now walking out the door. See how that works? These kinds of techniques can not really be taught. They have to be learned. They are born out of an attitude that you learn to use when you've been in the game for a long time and have had every insult and threat thrown at you that can be imagined.

You can't allow that stuff affect you in a negative way. Rejection happens to everyone, what separates the winners from the losers out there, is how they handle rejection.

Dude this thread was several years old. The guy who posted it is long gone.
