Fluency doesn’t arrive on a set day. One morning you just notice you stopped translating in your head.

Thresholds get noticed afterwards, never crossed on purpose. There is no morning you become fluent; there is a morning you realise you followed a whole conversation without the little lag of translating, and the crossing happened some unremarkable week before that. The arrival is always a discovery rather than an achievement.

So stop testing yourself for it, because testing is what makes the lag come back. Keep the contact going instead: the show, the conversation, the hour. One day you will catch yourself already across, and that is the only way anybody ever gets there.
