There are 2 very different approaches to coaching:
Positive: Teach others to love the strength of virtue, to love its goodness, power and beauty. And even more - to WANT to teach others to love virtue.
That is a great question to ask yourself about your next captains: Do my Senior leaders love teaching the Freshmen to love virtue?
Negative: Don't do this, don't do that, this is not acceptable ...
This style of coaching only creates athletes who fear your reaction, who fear the negative consequences.
That might work for a limited amount of time but eventually it builds resentment, hatred and disgust. They only do it to out of fear or to please coach, nothing really changes in their heart.
Lasting success, lifelong lessons and becoming a better human being do not include those ingredients.
