Exactly.
To me, putting your kids in sports is the same thing as putting them into the Boy/Girl Scouts or into playing a musical instrument. It's just ONE tool to help enrich their lives and help with their growth and development. The whole idea of "I'm going to push my child to be the best they can be and play like a champion" just does not compute with me. They already have a coach. It's THEIR job to push those kinds of buttons in your child, not you the parent. As a parent, in your eyes your kids should be "champions" anyway. Let THEM discern whether or not they actually play like champions. It's not your job to tell them they sucked. You're job is to be there for them and support whatever they want to pursue.
Maybe it's because my parents didn't do me that way. I played baseball and football from little league all the way through high school. However not one time did my parents ever even have a conversation with me about how I played or practiced. They supported me all the way, were at every game/practice, every banquet, etc. They always were proud of me and told me so, no matter how I played.
The main thing that my parents stressed with me was never quitting. If I started a season playing baseball or football, I HAD to finish the season. That was their one "non negotiable."
