The Big Picture Is Never Done

If you're learning something sufficiently complex, the big picture is never done. It's not like, oh, I painted that and now it's ready to go. So of course it's not all gonna be written down. The whole point is to learn in such a way where you maintain the salient points in the mind and continually glue them together over time. And eventually your models are stronger and stronger and cover more area and you can understand more.
