It doesn’t matter what you’re interested in, learn. Read. Study. Ask questions. Don’t accept answers. Poke at it with a stick, as I say. If there isn’t a problem, create one, simply as an abstract, just to have a perspective you haven’t seen before. Any reason to study a different angle is acceptable.
Twenty years ago, the things I was interested in, I thought I was an expert in because I knew more than my friends.
Now, I’ve spent twenty years thinking. I’ve answered thousands of questions but created legions more. The more I learn, the more I know that I know nothing.
We can’t grow unless we learn. We can’t learn unless we’re ignorant.
This is the way.
