It is said (and so I have also experienced) that we explore our unknown self through our writing. Secrets unveil, concepts clarify, and there is sometimes that ah-ha! moment that makes us realise “Yes! This is why! This is why life’s like that!”
Subsets of your universe decoded as thoughts and words flow over paper.
In contrast, I’m afraid there is little or nothing to decode in building buildings. It is a planned (in detail) and rehearsed process. Writing’s more natural and self-exploratory.
Just a dimension to the intriguing comparison you’ve made. :)
