We live on an island surrounded by a sea of ignorance. As our island of knowledge grows, so does the shore of our ignorance.

Insight: The more you learn about anything—whether it's history, fitness, your own family dynamics, or how your city actually works—the more you realize how much you don't know. It's a strange feeling that catches a lot of people off guard. You'd think expertise would feel like confidence, and it does sometimes, but it also feels like standing at the edge of an ever-expanding map where the borders keep getting further away. This matters because it explains why curious people often feel less certain than confident ones. That nagging sense that you've got gaps in your knowledge isn't a personal failure—it's actually the sign you're thinking clearly. The person who's absolutely sure they understand politics, parenting, or their own psychology is usually the one who hasn't looked closely enough. Real learning isn't about shrinking the unknown; it's about discovering how vast it actually is. The practical upside is this: if you're willing to sit with that discomfort, you get to be the kind of person who asks good questions and stays open to being wrong. That's not weakness. That's actually how you keep growing instead of calcifying into someone who stopped learning years ago.
