Quotes from Anson Dorrance

You can never be fit enough for this game.

What you do when no one else is looking will determine how good you'll be.

Competition is key to developing players. The only practice environment in which you truly develop a player is a competitive arena.

What it comes down to is intense desire. To get this winning edge, you need to build an indomitable will. This means you must be relentless; you must never give up.
