I really hate that one. To me it just comes across as victim blaming. Somebody makes you feel bad about yourself, but it's 'your fault' for 'allowing' them too.
I like this because it pushes the 'have self confidence' vibe. So, why do you feel inferior? Is it valid (no probably not). Then just carry on. So, if you don't believe in yourself, who will.
I'd say this is different to other people who deliberately try and make you feel like shit.
