"You cannot let down in preparation, conditioning, or psychological readiness. You must prepare as though your job is on the line, which it is every day. Nothing lasts forever. Things can be going fine and then, before you know it, it all can be take away. That’s one of the things that motivates me to keep working hard with little letup. If you lose that edge — particularly in coaching — very often you lose your job."
