That is an excellent question.
On the one hand, why not just go for better women? You got nothing to lose. You should keep your standards high, right?
On the other hand, why not just fvck her? It doesn't matter what a girl looks like, ***** is the biologically the same. And, I think all this "well she's a 6-7" talk is just a camoflauge for simple, everyday fear.
But on the other hand, 6-7s do occupy our time, energy, and motivation, which could help us get past the most important barrier of all: the barrier that stops us against perfect 10s. I hate that barrier, and it is something I want to get rid of, at all costs.
