notes: Coaches should be motivators and not dictators.

Coach Phil Jackson is a good example where people regard him as a Zen Master, rather than a literal coach figure.

This is a good principle where the objective was to emphasize positive perspective rather than highlight the negative action. I believe this theory improves the player's brain to imprint the positive aspect and replace the negative action previously committed. This provides better output as well as complementing the 'flushing' effect of players to recover from sports pressure especially in crucial moments of the game.
