I cannot find the source, but I saved this quote by Douglas Hofstadter about the process of writing, rewriting, and revising:
"It is the intensity of this process of global tightening and smoothing of a huge structure that was once implicit in one's mind but is now external and has its own unanticipated shape, life, and momentum, it is the power of this process of converting a set of once-intangible intuitions into a very tangible network of interconnected crystals, that I had forgotten."
