Look back at the last ten things you looked up just because you were curious. That list is a sketch of who you are.

Curiosity leaves a trail that nothing else explains. A search made because you genuinely wanted to know was not for a grade, a job or a conversation, which makes those entries a cleaner record of your interests than anything you would say out loud. Taken together they usually show two or three subjects you keep returning to without planning it.

Go and look at yours this week, properly rather than from memory. Group them and name the two or three themes. Then take the strongest and give it a real hour, a book, a course, a person who knows about it. Interests that get fed tend to turn into something.
