I think my problem was that I used to think too deeply, and talking out loud was a simple vocalisation of my my very deep analyses, not just of myself, but anything that happened to be on my mind.

I try to keep it shallow and superficial nowadays (something I was loathe to do in the past). I've thought and self-talked myself into too many black holes and cul-de-sacs. I learned that life doesn't have to be serious, and neither do the nature of the conservations that you have with yourself.
