Lombardi's coaching career reflects that motto --- we will pursue perfection, in full knowledge that perfection is unattainable, but in pursuing perfection in everything we do, we will find excellence. And, as history shows excellence he and those players did find.
It is an amazing story of how Lombardi found that excellence at the High School (football and basketball), College (Army), and then NFL (Giants, Packers and Redskins). The famous phrase of Lombardi that 'winning isn't everything, it is the only thing', takes on a new meaning when you learn that by winning he means this focus on details and fundamentals, and the pursuit of perfection. Lombardi's message is almost identical to that of the other iconic coach -- John Wooden.
I highly recommend the HBO documentary on Lombardi to all teachers and those who have a leadership role in their jobs. The move from good to great in individual and organizational pursuits, in my opinion, is tied up with these lessons from Lombardi.
