One aspect of the importance of validation is that, it’s not that I am agreeing with what you are saying, but simply that I listened and heard you.
That you actually got some idea or feeling of yours heard by me.
That whatever words I used, my underlying message was: “I see you”.
And so this releases me from needing to be some wishy-washy agree-with-everyone person and allows me to be myself, to find my voice with which to say, “I see you”. Because the “I” in “I see you” needs to be present.
And the more I am authentically me, the more I can see you.
