Pay attention, fellas!
is a strange thing. We tend to think it only happens to/with "perfect" people but that's far from the truth. There are plenty of things that men (and women) falsely believe are wrong about themselves even when others find that same feature extremely endearing.
Your goofy laugh? There's someone out there who can't get enough of it. That one hobby that you're SUPER nerdy about? There's someone who loves seeing you get so passionate over something. That 'horrible' nose you inherited from your dad's side of the gene pool? There's someone out there who thinks it's one of your sexiest features. Point is, don't give up hope and stop being so damn hard on yourself!
