Why try to prove you wrong when I agree?
The most valuable knowledge/skill to attain is to stop relying on validation, support and help from others. It's pretty damn self-explanatory, but we're wired to be tribal since in the past people had to rely on each other. Now everybody can fuck each other over without consequence since our society is all about individualism.
Same with feminism. Being a cheating whore has no consequences, so women will tend to do that instead of wanting a big family.
No constraints = total chaos.
Just become as self-reliant as possible, that's all you can do.
