Curious people learn more than clever people because they don’t pretend to already know.

Being quick is useful, and it comes with a trap. If you are used to having answers, admitting a gap feels like losing something, so the question goes unasked and the gap stays. Curiosity does not carry that cost. A curious person treats not knowing as the start of something rather than an embarrassment, and over a year those questions add up to a wide difference.

Find one thing this week you have been nodding along about. Say out loud that you do not follow it, and ask someone to explain. Ten seconds of discomfort buys you the thing itself.
