Mencius, the 4th-century BCE Confucian philosopher, argued that moral failure rarely comes from ignorance — it comes from distraction. His term was *fang xin* — the 'lost heart,' a mind that still knows what matters but has wandered so far from that knowledge it can no longer feel its pull. The interesting part: he thought this was the normal condition of any person under sustained pressure, not a character flaw. Product leaders face an exact version of this. After enough quarters of shipping, fielding complaints, and negotiating scope, you don't forget what your product is for — you just stop feeling it. The knowledge becomes inert. Mencius's prescription was blunt: you have to go back to the original encounter. Not the founding deck, not the user persona document — the actual moment before you had a framework for what you were building, when the problem still had weight. Find one person for whom your product either worked or failed in a way that surprised you recently, and hear it unmediated — no note-taker, no synthesis layer, no follow-up survey. The goal isn't new information. It's reactivating the feeling that made the information matter in the first place.

Think of the last time working on your product made you feel something unexpected — not satisfied or frustrated, but genuinely moved or unsettled. How long ago was that?
