Julia Quinn said this quote

She tried to remind herself that beauty was only skin deep, but that didn't offer any helpful excuses when she was berating herself for never knowing what to say to people. There was nothing more depressing than an ugly girl with no personality.It hurts, because deep inside, she knew who she was, and that person was smart and kind and often very funny, but somehow her personality always got lost somewhere between her heart and her mouth, and she found herself saying the wrong thing or, more often, nothing at all.
