wow; i snoozed for a day or two and you guys hit it hard.
It's time for bed, but I'll just add a plug for context.
Yes some players are born with desire. And context plays a huge huge roll in the cultivation of desire.
The book "Outliers" really hits that, as something like 9 of the richest 25 people ever were born with in a few years of each other.
Something in the environment (industrial revolution) made that possible. Great stories also there of Bill Gates and the Beatles.
So our job as coaches and parents is to pay big time attention to the context (especially the emotional context) we create.
(Arm injury guy: I often find players benefit in the long run from sitting out. They can see how foolish their teammates are for their approach to the game and their responses to adversity) (and remind me to comment on how to help him speed his recovery -- esp. the emotional aspects of it.)
