There is no desire more natural than the desire for knowledge.

Curiosity is not a discipline imposed from outside; it is closer to an appetite. Children demonstrate that before anybody teaches them anything, and adults who say they have lost it have usually had it trained out by years of being tested on what they never chose. The wanting is native, and what happens to it afterwards is the story.

If yours feels dead, treat it as a wound rather than a trait. Follow the smallest live question you have, even a trivial one, with no plan to be useful. Appetite tends to return once eating stops being an assignment.
