also it's the same like language learning, e.g., in Turkish, it is all about suffixes, the ending of the words; it basically has no fixed rules! it sort of goes with what sounds better...😲 wow then it became really hard to learn, but the interesting thing is once your ear got enough inputs or when is ready, it just makes sense.

I assumed when we don't force ourselves into learning, the brain is still subconsciously learning, and maybe that's the best, learning yet not really "learning."
