I didn't really start making cold approaches until I was old, after having read a pickup book (magic bullets) on one weekend. (before that it was warm approaches, social circle etc)
I got laid on my first ever attempt! In hindisight, it was just more or less the luck of
1)me being her physical type
2)her having just broken up with her bf and she was likely just looking to get laid that night. Just so happened I was the only guy with the balls to open her. Almost nobody approaches here in the UK, it seems!!
In fact, now that i've been at this for like 3 years, I STILL think that's basically always the case. i.e- You need to be her physical type. 'Game' can't make girls into you. But with approaching, you simply give yourself a chance to find a girl who thinks you're hot! It's the act of approaching that makes it kind of 'work' in the long term as opposed to some sort of magic skill in my eyes. I get laid a lot more than my friends who are about as good looking as me but who never approach. But I can't get NEAR to competing with my really handsome friends who very rarely approach, but instead get approached lol
In terms of how it went, I used an opener I read where I pretended to be the girls blind date and was like ''Sorry i'm late, Kelly! Traffic was awful. So, have you been waiting long?'' and just sat down next to her and started looking at the menu on the table. We bantered about that for a while, I tried to touch her here and there and at one point pretty much told her I thought she was pretty. I then bought us a strong drink, and soon after pulled her into a cab and took us back to my place to bone. I was like 29 and she was 18
At first I was like, 'dam, is it really that easy??''. I then proceeded to get rejected in my next 250 approaches or so until I got laid again. In fact, i'd say even now it takes me maybe 200+ approaches to find a hot girl who's into me and who I can get in bed
