When I criticize someone, I’m really saying: “I am better!”.
I say that I am better because of a soft, practically inaudible voice inside of me that’s saying: “You’re not good enough”. Every time that I criticize someone, I reinforce that small inner voice, giving it the strength to speak again and weaken me further.
This is a closed loop; a negatively-self-reinforcing cycle. It never ends . . .
. . . unless I refrain from criticizing.
Initially – when I wish to refrain from criticizing someone – I may still be criticizing them mentally, yet without voicing it. Later, as that self-destructive inner-voice weakens further, even the criticizing thoughts will cease. Once they do, I become free, strong, happy and certainly much more than merely “good enough”.
