Don't be afraid to go deep in simple sounding topics. The modern world is so full of learning material that there's the temptation to ingest as much of it as possible, but true learning happens when you give yourself time with one topic at a time. And I'd say this is more important than even, because generative AI is becoming great at precisely generating things, not so in understanding complex topics.

That said, learning the fundamental topics can limit your thinking first if they feel difficult, so it's an interesting question how to keep the naïve creativity of the beginner that's something that can really help when building with AI because there are less limitations in your thinking based on how things used to be.
