I think this stuff only works on club and party girls who are full of themselves. A normal nice girl who is not full of herself does not respond well. I think this shit ruins your chances with those kind of girls

You will meet 3 types of girls. No, maybe, and yes. Nothing will work on the no girls, they simply aren't interested. Maybe girls take a little work to turn into yes girls. Yes girls are all about recognizing they are a yes girl, and smoothly moving them to a place to have sex in.

I'm referring to pick-up techniques in general. Within the broad definition there are techniques that don't work on any girls, such as NLP, but then there are necessities like confidence and kino escalation to get the maybe and yes girls.

What specific "stuff" are you referring to?

Every girl is different. Find out what PU style matches with your personality. Go out and PU using the style that suits your personality. You will weed out all the women who are not prime mates (eg them rejecting you) and you will be left with a good amount of women who will enjoy being with you.

The key is to approach a lot of women so your odds go up. Lets say 1/5 women you approach like you. Approach 30 girls and 6 girls like you.

The great thing about this is if you get into a relationship, you won't feel like "OH SHIT! I'm all out of material!". You picked a PU style that matched your personality so you can keep being yourself and she will be into you.

Confidence and kino I agree are good.
I mean text routines, being ridiculous in text, cocky funny, being to much about yourself etc, cutting off text convos, seems like to certain girls you come off as a tool

Text routines: Not a fan of routines in general, I'd rather make up my own stuff on the spot. However most text openers are good for mixing it up from the usual "sup." I use text for figuring out logistics and asking the girl out. I've never been blown out doing that, but I have been blown out really badly trying routines.

Being ridiculous in text: If the girl is playing along, she's already a yes-girl, or a maybe-girl tipping towards it.

Cocky Funny: I think the point of this is for guys that don't have a base level of confidence. They have to overcompensate, and the funny helps them reduce the number of girls saying "you're a cocky son of a bitch" If you're already confident, you don't have to do cocky/funny.

Being to much about yourself: Not sure what you're talking about

Cutting off text convos: This is for guys that will happily text aaalllll day with a girl. They don't realize how it comes across as "i have nothing better to do." No-girls won't give a shit that you stopped talking to them. Maybe-girls will realize you have a life, and yes-girls won't mind either way.

One text-game advice that I use regardless is not replying any faster than she does. Obviously if there's a time constraint you don't want to play games, but I find people in general will be more likely to respond if you match their pace or go slower. It also lets you know if she's a yes-girl if you're taking 20 mins to respond, and she's responding immediately.
