When you're deep in a product cycle — sprint reviews, roadmap debates, stakeholder updates — your sense of who you are quietly gets outsourced to whoever is loudest in the room. The 16th-century philosopher Michel de Montaigne noticed this mechanism and built a practice against it: he would regularly retire to his tower library not to think about himself, but to catch himself thinking — watching which opinions he'd absorbed without choosing them. What he discovered wasn't a stable self waiting beneath the noise, but something stranger: selfhood as an ongoing act of *noticing what has silently colonized you*. For anyone navigating product work, where external pressure constantly scripts your reasoning, the practical move is less about meditation and more about Montaigne's habit — periodically asking not 'what do I think?' but 'when did I start thinking this, and whose room was I in?'

In the last two weeks, name one position you hold — about your roadmap, your team, yourself — that you adopted in a room rather than reasoned to alone. When did you last check whether you still actually believe it?
