I'm 5'5 and when I've told people that I believe my height is hurting me in dating, I've gotten responses like, "You need to own your height."

What does that even mean?

For the record I do not lie about my height to women nor do I even talk my height with girls I'm interested in. They already know I'm short, I don't need to bring more attention to it. The vast majority of girls have enough decency to not bring it up either.

Yes, I do list my height as the primary reason why I don't succeed with women.
