Success in busin as is often a function of how comfortable you make the people around you as much as it is the quality of your work.
That can mean personal hygiene, clothing, speech mannerisms, shared cultural touchstones (sports, movies, whatever), and sometimes even (though often subconsciously) race.
You want to succeed? Master the art of culturally complying with those in power as much as you can. Maybe it kinda sucks, but humans are tribal. It's instinctive, and it's going to happen no matter how much we may rage against it. Might as well take advantage of it where you can.
