So from a training wheels perspective, we might totally eradicate words like "should". I did this! It was really helpful. But once I had removed the word from my idiolect, it became unhelpful to still be treating it as being a touchy word. Then I heard my mentor use it, and I remembered that the point of removing the word wasn't to not ever use it, but to train my brain to think without a particular structure that "should" represented.

I tried this as well. I spent a year not using words like "should" and "fault". I then went back to using them when I started my full-time job because those words are too useful, and I regressed, at least partially, to my old way of thinking.

Old patterns come back if you're not careful. The training wheel metaphor is likely counterproductive here.
