Your interpretation of a few of the
PUA type things (negs, push pull and so on) isn't quite accurate. However that doesn't really matter since even in their correct form they're ineffective and fucking stupid, so your advice of 'just don't' is pretty much on the money.
The problem is that you're cutting out stuff that won't work and replacing it with a completely different type of stuff that won't work. This is less your fault and more of a massive systemic problem with the concept of pickup in general. Being attractive is something you 'are', not a set of specific conscious things you 'do'. Attractiveness has to be developed as an intuitive subconscious kind of thing through experience.
It's a general cart before the horse problem. People see attractive people behave in a certain way, or get success with the opposite sex one night, then go back and attempt to post hoc rationalise what was going on. This can be practically anything, from being disinterested to being focussed, from being very physical to not physical at all. The problem is that these rationalisations are often incorrect and barely ever adaptable to other situations.
Consciously micromanaging your own behaviour looks fake, forced and creepy no matter what you do. People spot it easily and it makes them uncomfortable. Any person new to pickup who is not confident is going to balls up acting cool and confident regardless of the specific method you gave him. This is why stuff like push pull, negs, kino etc are really ineffective for most guys, and it's easy to visualise how a misplaced bit of push pull or kino would look terrible, but the same thing is true of your more conventional tips (aside from washing of course):
- Standing straight - People who consciously try to control their posture in a conversation generally look awkward as fuck. Same thing with 'finely tuned body language'.
- Compliments - Often used in the old school pua stuff, and they can be just as weird as negs in the wrong hands.
- Self Kino - Picture some dude in a club wearing a fedora and blazer, rubbing himself like he's in a fucking timotei advert. That would happen. PUA's are that weird, trust me.
- High intensity focus - Huge potential for creepiness with those who have poor social intuition. A while back a pickup instructor for RSD was talking about strong eye contact. People started filming themselves staring into their webcams and uploading the video of it to the rsd forum to see if they were doing it right. Yep. Weird.
The little golden nugget of truth at the middle of all the bullshit of pickup and seduction is this:
'Go out and talk to a lot of girls. Have some guts and push yourself into situations that might intimidate you a bit. Think for yourself and figure out what works best for you'
Anything other than that is just surface layer flim flam and is generally going to fail to deliver, regardless of what the tips and principles you use.
But if that's what you want to do, then sure whatever.
