This idea is dumb as hell and falls apart if you spend one second in the real world. Everyone knows for a fact that literally any woman can get a guy if she wants to. There are millions of men out there just plain desperate for someone of the female gender, it's not like they're picky.
For a few years now I've seen charisma as this weird-ass superpower. It is based in absolutely nothing good or meaningful, but having it or not having it can make or break a person. If she had no charisma, she'd be nothing. But she has charisma and looks and that's the sole reason anyone even knows her name.
If I could change one aspect about myself I would give myself charisma. It makes a lot of things go so much further.
