learn the life lesson of resiliency. You work hard for something it may not happen when you think. But keep fighting and someday something you work hard for will pay off. It's hard for a teenager to see the long view now but it will happen at some point maybe not sports but in more important things in life.
I'm in education and that is one of the hardest things for kids these days is bouncing back from disappointment. It's hard to help them through but worth it.
