W. Timothy Gallwey's Inner Game framework distinguishes between the conscious "Self 1" that instructs and judges, and the unconscious "Self 2" that performs.

The core argument is that internal interference, primarily from Self 1, hinders optimal performance by causing tension and self-doubt.

The Inner Game methodology focuses on techniques to quiet Self 1 through non-judgmental awareness, focused attention, visualization, and trust in Self 2.

Ultimately, the aim is to achieve harmony between these two selves to unlock potential, enhance learning, increase enjoyment, and redefine success beyond mere outcomes.
