You've probably shipped something that technically worked but quietly disappointed everyone — including you. The gap between 'meets spec' and 'actually matters' is where most product work lives, and it's uncomfortable to name. The Jain philosopher Kundakunda, writing in the 2nd century CE, made a distinction that cuts right through this: dravya-paryaya versus bhava-paryaya — the difference between an external transformation (a feature ships, a metric moves) and an internal one (the person using it is genuinely changed). Modern behavioral researcher B.J. Fogg reaches a similar edge in his motivation-ability-prompt research: most interventions change behavior only as long as the prompt is present, because they never touched the underlying state. Real product work — and real self-work — asks not 'did the thing change?' but 'did the person change?' That's a harder question to put in a roadmap. But it's the one worth carrying into your week.

Name one thing you shipped or decided in the last month that changed a metric but left the underlying human problem untouched.
