The real sting here lies in that ordering—wisdom comes *first*, suggesting that understanding others is the necessary, humbler work we do before we're ready for the harder task. Most of us spend our lives collecting observations about what makes people tick, why they disappoint us, what they want, yet we treat self-knowledge as something that happens naturally, almost accidentally. But Lao Tzu insists that spotting your own patterns—why you repeat the same mistakes, what you actually want beneath what you think you should want—requires a completely different kind of attention, one that most people never quite muster. Consider the colleague who brilliantly reads everyone in the room but has no idea why he alienates people, or the friend who offers perfect counsel to others while remaining baffled by her own choices: they've mastered the first half and missed the second.
