How to Learn About Everything (or: How to be Curious) from Metamodern.
This is a great article espousing the polymath method of learning. That is to say, reading about a wide variety of topics to gather a greater understanding of the whole picture can be useful. In summary, a curious thinker doesn’t necessarily have to study something in depth and obtain mastery before moving on to the next subject in the same way one studies for a test. Rather, the polymath’s understanding is fostered by breadth of reading and learning; we build our understanding of one concept by reading about it, moving on to another subject and finding ways to relate it to the things we already know, and eventually circling back around to the same subject to build even further.
