Found this thought on coaching in Chad Harbach's The Art of Fielding pretty interesting. One of the main characters is reflecting on what is needed to be an effective coach and believes that what one has to do is:
"...look at each of your players and ask yourself: What story does this guy wish someone would tell him about himself? And then you told the guy that story. You told it with a hint of doom. You included his flaws. You emphasized the obstacles that could prevent him from succeeding. That was what made the story epic: the player, the hero, had to suffer mightily en route to his final triumph."
