Liking something before it was cool isn’t the point. Liking it after it’s not cool is.

Taste used as a credential is about timing and status rather than about the thing itself. Being early proves you were watching the right signals; staying after the crowd leaves proves the affection was real. The second one is harder, because there is no audience for it and no advantage in mentioning it to anyone.

Find something you quietly dropped once it stopped being impressive to like. Spend an hour with it this week and tell nobody you did. Whatever survives that test is actually yours.
