Pay attention to what makes you say “wait, really?” That reaction is your curiosity waving at you.

Surprise measures the gap between what you expected and what is true, and it also says something about you. The things that make you stop are not random; they mark the subjects where you already know enough to be startled. Boredom points nowhere in particular, while surprise points somewhere specific.

Keep a note of whatever made you sit up this week, even briefly. One line each is enough. Look at the list in a month and you will see what you are genuinely interested in rather than what you claim.
