My approach to dealing with lots of concepts is pretty much stolen from how babies learn language. Grownups talk around non-verbal babies as if they're not there. We refer to all the objects in the room (or anywhere else) whether the baby understands them or not. "How was your day at work?" "Oh it was okay, but traffic was bad so I didn't have time to get my usual coffee." Babies don't understand what traffic or coffee is, and they don't have to. They still eventually learn the language and really focus on the things that matter to them. At some point, a lot of us try to simplify by reducing the number of concepts we're exposed to, and we try to feel like we understand those fewer concepts. I've switched my approach to just being immersed in the way experts talk about the field, and just getting used to used to not really knowing what most things mean. It turns out you get a ton of information this way. Not only do you learn the vocabulary before you need it (reducing the time required later when you eventually need it) but also you pick up a sense of which things are fundamental (they come up a lot in conversation) and which things are extraneous detail (they're barely mentioned or only mentioned when something goes wrong).
