You can drill down on where hunger comes from and figure it out from there, but there absolutely has to be a sense of urgency if you're going to play tennis because you're the team - there's no one for you to rely on but yourself.

What I've seen historically is winning is a major aloe. It solves a lot of problems.

Us going out there and performing our best. That's how I define success. I'm not going to define it for us by the wins and the losses as much as by the effort and how we handle ourselves.

You have to be extreme to be exceptional. I couldn't revel in being number one. I had to get to zero. When my fitness was at its peak, I was intimidating. I made guys cave in.
