Writing is hard. I have always known it is hard. The rhythm that I have developed for the 25th Anniversary update is to move between structures and pedagogy.
What this means is I am alternating between adding structures and editing the learning part of learn improv. Some improv structures are just plain odd and and inexplicable. The effort to decode the gibberish is tiring. This is when I move over to pedagogy or taxonomy.
So when my brain tires of trying to understand the opaque elements of the impossible to manage long form structure Ding Dong I move to editing LACE instead. Hence LACE is nude and improved. With all new profanity!
