Daygame was brutal even in 2005-2006 when I first got into PUA stuff. I could never do it. I think the harshness of daytime lighting coupled with a lack of an attractive wingman to soften the blow of my ugliness and a lack of alcohol in a girl's system made it impossible. Plus everyone can hear and see everything you say and do. Most girls won't even stop to talk. The few that do clearly want nothing to do with you and are just annoyed you are wasting their time.
The other problem is if you're ugly and want to pick up girls on cold approach, you will need A LOT of girls. Like out of 10 sets of 2 girls in a night at a bar, maybe ONE might be basically friendly and talk to you and show an interest. So that's like 1/10-1/20 girls. It's not easy to find a place in the daytime that you can just spam 20 girls back to back like that without getting in trouble. People do college campuses but I'm a firm believer in "don't shit where you eat" if you're a college student there. And if you're not a college student, you expose yourself to legal/harassment risks that way.
I have never understood how day game works for anyone. You must have to be really good looking for it to. Like LAHWF on youtube good looking tier.
I will share one of the most traumatizing videos I've ever seen:
This video's 5 years old and I'm pretty sure it's haunted me now for 5 years straight. Why? Because out of hundreds and hundreds (maybe thousands) of cold approaches, I could never dream of having a single response this positive and effortless. And there's clearly no skill to what he's doing. He's awkward as fuck. It's just genetics.
