Mencius, the 4th-century BCE Confucian thinker, argued that moral failure rarely comes from bad intentions — it comes from what he called 'lost heart,' a gradual numbing that happens not in a single dramatic moment but through small habitual neglect. The heart doesn't shatter; it drifts. Product managers know this shape intimately, though they rarely name it: the sprint where you stopped asking why the metric matters, the quarter where stakeholder appeasement quietly replaced user advocacy, the roadmap that grew heavier with inherited assumptions nobody wanted to question aloud. The drift is invisible because each individual step felt reasonable. What Mencius prescribed wasn't an audit or a reset — it was a practice he called 'seeking the lost heart,' a deliberate, repeated act of return. Not dramatic reinvention, but small, honest retrieval. Before you open Monday's tickets, it's worth spending five minutes asking not what you're building, but which original conviction about what your product is for you've been carrying less carefully than you once did.

Which original belief about what your product should do for users have you stopped defending in meetings — not because you changed your mind, but because it became easier not to?

Drawing from Confucian Philosophy (Mencian) — Mencius (Mengzi 孟子, c. 4th century BCE) — particularly Book 6A, Chapter 8 on 'qiu qi fang xin' / seeking the lost heart
