There is a great video of Dr. Manning a BYU professor and sports psychologist
Where he talks about #6, especially with youth sports, to be focused on tasks and not outcomes. This shifts the focus away from things we do not have control over (outcomes) to things we do (tasks). I coach multiple youth soccer teams and making this shift in how I coach (and parent) has resulted in a huge change for me in how I see the games and the kids (mine and the others I coach).
