Well, there is no set boundary what belongs in the hierarchical notebook
and the evergreen notes but I'm starting to lean in combining the two
together with a flat hierarchy. Nonetheless, I was able to make more
insights from separating them so it's worth it.
Some more notes on them, though it's becoming more broad with the
perspectives this time. There is a backlog of them more, I just need to
process them this morning (or evening). This will eventually diverge
into more concrete skills now.
