I don’t 100% agree with this. Looks help to an extent, but once your good looking “enough” like a 7, confidence and social skills will carry you so much further. Looks can get ya in the door, but that’s about it.
I also know a ridiculous amount of people that are good looking, like 8+, but because they lack confidence and social skills are perceived so much lower.
I consider myself decent looking, probably a 7-8, but if I’m at a bar or social event I will go toe to toe with just about anybody lol.
