Sefu Bernard has a post on his Thellabb.com site based on an interview/quote with Mark Cuban based on the following question:
“How can I work in the professional sports?”
The advice Cuban gives is that professional sports is very difficult to get involved with due to the demand, so don't bother.
I see the same question from athletes and coaches - "how can I become an elite coach" or how do a 'turn pro' - my answer is the same as the conclusion of Sefu's article:
"Persistence pays off."
