Among the systems I system-think about are systems that produce self-expression and systems that produce creative work.

Lots of people like to think about efficiency because thinking about efficiency is easier than doing work...and avoiding work is one of the definitions of efficiency.

Or to put it another way (and in the context of writing), thinking about efficiency doesn't put words on the page and what's in our heads is not the result of our creative acts.

Efficiency arises from the work, not vice versa. Self-expressive work arises from inspiration. The friction of inefficiency is often a symptom of important self-expression.
