I was embarrassed how little I could say after countless hours of flash cards and other methods. I'd literally just comprehend nothing if someone talked to me. But after a few months of just listening it became much easier. I've thrown all the Anki cards away afterwards, it was just a waste of time.
Could I speak Japanese at that point? No not really… I even had a Japanese spouse! But we spoke mostly English at home. I could read quite well, but conversation was very challenging.
Then we moved to Japan. Despite not having a job that requires me to speak Japanese, I got enough live exposure just from chatting with people at the gym or in social activities that now, a few years later, I’ve backfilled all that conversational fluency that was missing. No special extra effort required, just living in an environment where I used the language reasonably often.
Anyways, the point is that all the time spent in Anki laid a rock-solid foundation that merely needed activation in the right environment for active fluency to emerge. Of course I no longer do my daily flashcard drills (and I’ve forgotten how to write quite a few kanji as a result) but the work paid off.
