We are probably connected to everyone else in the world by six degrees. This means if you know a person, you are one degree from them. Someone they know is two degrees from you. Someone that person knows is three degrees from you, and so on until the sixth person. So, it has been said that everyone on the planet is six degrees or less from each other.
I'm interested in following this thread as it pertains to greatness in different contexts. This blog and it's associated audio interviews and podcast will do just that - follow greatness for six degrees to see to whom it takes me.
