Champions are not the ones who always win races - champions are the ones who get out there and try. And try harder the next time. And even harder the next time. Champion is a state of mind. They are devoted. They compete to best themselves as much if not more than they compete to best others. Champions are not just athletes.

And athletes in general are, in this moment, the biggest ambassadors that our country has.
