I hope this topic hasn't been posted before, I certainly couldn't find it.
Let me preface this by saying, I don't have kids, maybe I don't understand.
Listening to a local sports radio show this morning, I was reminded of something.  Up to a certain age in sports, they quit keeping track of wins, losses, even the score.  
That bothers me a bit.  As much as you learn the fundamentals and how to compete at anything, you also learn how to WIN.  
I'm just curious what your thoughts are.  I see both sides I think, but I'm interested in some arguments.
