It's not like what this guy is vomiting is all that off-base. I could only stomach the first video so I can't speak for the other ones, but the first one actually did make a lot of sense to me.
That being said, he took about 12 minutes to say what any asshole who's fucked some strange pussy could convey in less than a minute. If you are confident, it tends to make itself known. If you are not confident, this also seems to make itself apparent. Women like confident men, not ones without confidence. So no matter what your approach to women is, it should be handled with confidence. This necessarily entails abandoning all negative thoughts. And of course, if you get rejected (like we all have) you shake it off and get yourself back in the game.
Personally, I'm starting to like this guy a little. He's found a major niche in that there are always going to be a bunch of mongoloids out there somewhere who don't know the first thing about the way the world works. He's simply taking advantage of this and, like he's obligated to do, has used this to separate fools from their money. If I wasn't worried about crossing paths with myself in the mirror each morning I'd probably look into doing whatever it is this Arash character is doing.
