Lending Voice to Thought

A line of scripted dialog has been traveling repeatedly through my thoughts. It was spoken by Toby Ziegler, a character on the television series West Wing. It's his line -Toby's line- ruefully, dare I say woefully delivered, that I continue to ponder. I'll paraphrase as I don't recall the exact quote. It goes something like this:

"I lent voice to thought, and that was my mistake..."

I've been thinking about that turn of phrase ever since I heard it. I have regrets of words I have spoken that should have been left unsaid. Lending voice to thought. It's something to be considered well.
