If you cheat yourself in practice, you'll cheat yourself in a game; and if you cheat in a game, you'll cheat yourself for the rest of your life.

Errors, mistakes, and humiliations are all necessary steps in the learning process. Once they have served their purpose, they should be forgotten. If we constantly dwell upon the errors, then the error or failure becomes the goal.
