“You know what charm is: a way of getting the answer yes without having asked any clear question.”
That's good. I'd also call that buy-in. When someone is ready to say yes before they hear what is asked of them.
Today I had the kids in climbing club start lying on the mats on their stomachs and then they had to run down this hallway of mats and drop down all the way on the last mat and stand up and run back to the start and lay down as fast as they could. The most important thing is that the kids like it and it's fun. But I like to think about how much coordination goes into sprinting, lying down flat, standing up and sprinting again. It seems like it would do a good job of getting your body comfortable with moving quickly in space and applying force quickly.
I think fun stuff like that creates buy-in. Moving your body in a new and different way that is fun and competitive.
