Insatiable Curiosity
Curiosity is not a trait you either have or don't — it is a practice. History's greatest polymaths treated every encounter with the unknown as an invitation rather than a threat. Leonardo da Vinci filled thousands of notebook pages with questions about things most people never thought to ask: Why does the sky turn red at sunset? How does water move around an obstacle? Why do woodpeckers not get headaches?
Cultivating curiosity means building the habit of asking "why" and "how" one level deeper than you normally would. It means pursuing tangents when they arise rather than suppressing them. It means treating confusion as signal, not noise.
Practice
Keep a "question journal." Every day, write down three things you encountered that you don't fully understand. Pick one each week to investigate deeply.
Historical Example
Richard Feynman famously kept a list of "open problems" in his mind — questions that lived with him for years, primed to receive insight from any domain he explored.
