Well said, Cherl-Anne!

Sub-vocalization and/or talking to ones self and/or muttering...

...are the most potent and powerful methods of delivery by habit; indeed the most potent and powerful enforcer of ones own box. The only thing more deadly?

Off handed remarks to other people, because the social reality is we generally 'talk' or 'write' to hear out and 'know out better' our own ideas.

'There is no rule more binding than those of ones own making' and the ways of 'making' are many and often very subtle.
