The Importance of Commitment

I would violently agree with you that physiology is vastly overrated and psychology is underrated. A wonderful discussion I had on deck with USA Swimming coach David Marsh, who said commitment was the most important quality for an athlete to have. And we all know those things are critically important, but it's hard to teach. Where's the commitment meter? Where's the self-determination-o-meter? where's the thing you can wear on your chest that shows you the level of resilience under pressure?
