I give the guy in the video props for going after girls and being able to get the girls with his disability.
But to say that looks do not matter at all is complete crap. Looks do matter. If you go to a job interview at a huge company and you come in with a t-shirt and jeans, what do you think the likely hood they are going to hire you? First impressions are important and it is very hard to recover from a bad one.
When it comes to picking up girls, most girls size you up within 15 seconds usually less. And guess what, they sized you up base on your looks and nothing else. Why else is the whole peacock thing so important when it comes to picking up girls? Everyone makes judgments base upon how people look. Yes once you start talking to the girl her impressing and/or judgment of you can change, but again going back to the first impression.
Presentation matters. LOOKS don't matter. Dressing well and looking well groomed is about PRESENTATION. It shows that you take care of yourself, and that's important. LOOKS, on the other hand, become secondary once you have your presentation down SOLID. Present yourself as dirty and insecure, and it will not matter how good you look. You'll just be the good looking, but dirty and insecure dude that no one wants to hang around.
