I think what he has going for him is that he is confident, and acts like a normal person,
99.99 percent of men cannot be confident and normal cold approaching a girl. So what he is doing is beyond the reach of most men already.
This gets results. Its not top game but it gets results because you will run into interested girls.
Not very many to women, not much genuine rapport beyond friendly topics Not much teasing to spike interest. No reality pacing, lover frames, and so on.
This is the next stage. Once he gets so comfortable with being just confident and a normal person "during a cold approach" then he can move on to being "sexy and flirtatious" during a cold approach.
I dont think you can skip to that stage before being at the stage he is at now.
Most guys are awkward and come across strange during a cold approach and they are trying to jump to being the sexy, flirtatious guy without first aiming to reach the calm, confident and relaxed stage even if its just friendly and social and not very sexual.
These are the ones who say I have been doing this "for years" and I have not had a single date.
If you just come across as a social, friendly and confident guy and just not look like a homeless person and approach consistently you will get dates. Its pretty much inevitable if you put in the numbers.
Like lets say a guy is in a city like London or any city above a 1 million population.
He just goes out for a walk for 1 hour on a busy street everyday.
Lets say he meets 6 girls in that hour (10 min per approach) which is totally reasonable.
In a week he can meet 42 girls, in a month around 180. In a year even if he takes 65 days off, he can meet (300x6) 1800 women!!!
That is with just ONE hour a day. Nothing heroic but just being consistent.
If you are just being normal, confident, friendly and cool doing this and weed out all the nervous ticks, you are going to get dates.
Even if he gets 1 date in 50 approaches, he is going to be averaging 3-4 dates per month. Which is a better dating life than most normal guys have.
Once you are here, you can build up to being sexy, flirtatious and taking your Game to the next level. Just the fact that you can approach consistently and also are going on dates will boost your confidence.
But most guys never get to this "normal" stage, they do a few approaches here and there nervously and awkwardly and then pontificate on how to become the "smooth sexy guy".
Instead they should first be aiming to become the normal guy, comfortable with doing a cold approach, expressing intent and having basic conversations and going for the close.
