I do not think much of a man who is not wiser today than he was yesterday.

Growing smarter beats staying right

We live in an age of stubborn certainty. People defend their positions like fortresses, collecting evidence that confirms what they already believe and dismissing anything that challenges it. Lincoln's standard cuts through this: wisdom isn't just about what you know, it's about whether you're actually learning. Not just accumulating facts, but genuinely becoming smarter, more thoughtful, more capable of seeing what you missed before.

The tricky part is that real learning often feels uncomfortable. It means admitting you were wrong about something, or at least incomplete. It means reading the article that disagrees with you, having the conversation that makes you reconsider, noticing where your thinking has blind spots. Most of us resist this on some level. We'd rather be consistently ourselves than constantly revised versions of ourselves. But Lincoln's point is that the person who stays the same from year to year isn't staying stable—they're just declining more slowly. They're choosing comfort over growth.

What makes this feel urgent now is how easy it's become to outsource our thinking. We can exist in bubbles, algorithmic or social, where our existing views get endlessly reinforced. The question isn't whether you're smart enough. It's whether you're brave enough to be wrong, and curious enough to care.
