This applies to other things, in my experience. In making a drawing, for example, a mental dialog can go one of two ways:

- "this is wrong", "that line can't be right", "the shadow doesn't work"

or

- "how does this line relate to this other line?", "how does the light hit this plane", "what shapes does this decompose into?"

The critical dialog option leads to bad and abandoned drawings. The constructive dialog option leads to restatements and completed work.
