Me neither. But my brother did! Yesterday he finished his second marathon. He's always been an athlete, but until last year, he was never really a runner (although his years playing college basketball were definitely good training).
Bill has shown time and time again that when he focuses on something, he is FOCUSED, MAN! You can't steer him off course once he's decided he's going to do something. The fruits of this, in addition to his marathon accomplishments, include his own business, a degree from Cal Berkeley (boooo Bears! Give 'em the axe!), and a beautiful family of little scholar/athletes. Bill is never satisfied with his past accomplishments, but it's a healthy dissatisfaction. It's ambition-fuel that pushes him to do more.
I'm excited to see what he does next. Congratulations, Bill! Love you bro!
