"Reading the documentation end to end" is a superpower.

Some documentation is a bit large for this, but less than you think because it gets faster with practice.

I'd also mention "don't be afraid to source dive on OSS stuff", you'll be slow at first but being able to jump into other's people code and mentally reverse engineer their intent/architecture grows with time and is also a superpower.

(to the point where I often read the code first then check the docs and/or the tests to see if what I plan to do is explicitly supported or just incidentally going to work)
