These YouTube videos are all staged.
We should only rely on our real-life experiences, and by that I mean watch the good-looking guys around us and how well they do.
My cousin was very good-looking (still is but is now married to an average girl), 6'1 too.
He could come at my school and some of the girls who would never touch any of the incels in my class would throw themselves at him.
That said, I've also watched cold-approach many times and he was still rejected 90% of the time, but always very politely.
Don't try this if you're not tall and good-looking.
That's why those videos are bullshit, and I kind of believe the girls int his thread when they say they would reject this guy.
And for the 100th time, a phone number means jack sh*t.
