PERSISTENCE

Winning is never really about a single game, or product, or performance.  Winners know how to succeed over the long haul.  In fact, they know that winning is defined by repeat performances and increasing achievements.  Winners never give up, never accept defeat, and work as long and as hard as it takes to get the job done right.  Winners commonly say, "Don't tell me why I can't do it.  Tell me how I can get it done.
