One thing I notice about my writing habits given the mechanics of blog writing - and this could be substituted for earlier iterations of journaling and notetaking and sketching and the like - is that upon abstracting from a given set of relations, or state of affairs, you are left with a workable concept. Once you get the concept down, it then starts to change, as you start using what you've iterated to start focusing on the incoming data and experience, organizing them and then comparing them, and you start to see things in a new light, which at the same time feeds back into comparisons with the concept, changing it by either altering it to better fit the facts, or adding additional caveats or even compounds to better capture things. Rinse and repeat.
