> They take some vague feeling they’ve been thinking about, dig into a bunch, write down what they’ve discovered, realize half of it doesn’t make sense, delete most of it, write some more, realize the new stuff contradicts itself, panic when they realize they don’t understand the topic as well as they thought they did, talk to other smart people about why that is, learn something new that reminds them of this other thing that might tie into the second paragraph, discover that this thing they believed before they started writing isn’t actually true, realize that if that thing isn’t true then this other thing is probably really important, and so on endlessly. I love this sentence. It really captures the iterative nature and messiness of learning.
