Counterintuitive advice
I often think about this advice a friend gave me regarding maximizing playing time for my son. He asked, "What does he do that forces the coach to keep him on the field? Whatever it is, invest more time in that. Too many kids spend all of their time trying to fix their weaknesses. But the kids that play are usually the ones with a loud skill."
I ask myself this question often, especially during the offseason. I'm sharing it here in case someone else finds it as useful as I have.
(The hard part for my high schooler is that the true answer to the question is that almost never makes mistakes. He's always where he's supposed to be. He's basically an on-field coach. But it takes a long time to demonstrate that skill.)
