Its who you are working with and building more contacts. The world of Coaching, and my own game S&C, works just like business in that sense. Its all about relationships and in the modern world distance is generally not an issue for at least build a base of a relationship. I have contacts from the NFL to AFL to EPL to La Liga to Sweden, basically all because of 2 people, both i got to know online and eventually met face to face.
That is the world now.
