Social skills related facts that you have learned in your life.
Being likeable and charismatic is actually more beneficial for you than being super "book" smart. Doesn't matter where you're from, as long as you're not a meat head, if you're smart enough and likeable, your life will be great, doesn't even matter what race you are, even racists will find annoying the fact that they can't hate you, and many won't act racist to you simply because other people likes you a lot.
Work that EQ more, and you may end up in a position of power. Extra points if you're handsome.
Being arrogant will take you nowhere, even if you're smarter than the guy next to you, if he's likeable he'll be promoted faster than you.
