Knowledge is like money: to be of value it must circulate, and in circulating it can increase in quantity and, hopefully, in value.

Insight: We tend to hoard knowledge like it might run out. We finish a book and feel like we've won something, so we keep it locked in our heads, bringing it up only when it might make us look smart. But knowledge actually works the opposite way—it grows when we give it away. When you explain an idea to a friend, teach someone a skill, or even just think out loud about something you've learned, you're not losing it. You're strengthening it and often discovering angles you'd missed before. The money comparison is particularly sharp because it exposes how we misunderstand value. A dollar sitting in a drawer is just paper; its power only emerges when it moves, when it's spent and traded and circulated. Same with what you know. That productivity hack you discovered? It matters more when you share it. That lesson from a mistake? It becomes wisdom only when it helps someone else avoid the same pitfall. The paradox is real: the more freely you let your knowledge circulate, the richer both you and the people around you become.
