I think that appearance is more than skin deep, both in and out of the hobby world. I find extreme cockiness ugly and when I run across someone who is so convinced their shit don't stink, it causes me to see their "ugly", no matter how hot or handsome they may be. Personality does make some appear better looking.
Although I think this is something that only rings true for grown ups lol. If you asked me this when I was a teenager or in college, I would have told you its all about looks and what kind of shoes they wear
