What is the belief system of a player?

The player today believes in their development and their skills, but when things go wrong in a match, they handle the challenges and don’t let the things that go wrong affect performance. They allow the challenge to flow by or pass by like water under the bridge, like a stream. The mistakes, bad calls, flow like water and pass by,once the mistakes have gone, the bad things that have happened only then development can occur and focus on the match can happen.
