When we see our child create, it strikes a chord in our soul that brings us joy. We're "happy" when they clean up their toys, but we're "thrilled" when they give us a drawing. It's the same with soccer, if we give them a chance. If we allow them to create, the game will be better for them and better for us.
As Leonard Read said,
"To hamper Creative Energy, in any manner, as it attempts to manifest itself in mankind, is to thwart Creation. Standing against Creation is no role for little, fallible man!"
They may not be doing things they way we'd like, but if they're doing no harm, who are we to "correct" them. Our children naturally want to learn and explore; they just don't always want to do it according to our "fallible" plan.
