Scoreboard vs Mastery.  At the end of the game you take your team to McDonald’s for a treat.  The first thing someone is likely to ask the team is "Did you win?”  That puts a lot of pressure on the players to produce a scoreboard win, something that is not totally within their control.   However if we as adults reprogram our question to "Did you do a good job today?” we are now asking a personal question that the player has complete control over.  The player might respond "I gave it my best” or "I could have worked a little harder on my throw to first.”   Both are things the player has responsibility for and control of.
