Curate, connect, and discover
I wanna see a bilingual person that doesn't have to search for words and has a great vocabulary but, however, still has to ask for a defenition of a certain word they didn't quite understand in someone's speech from time to time.
Non-native speakers (and native speakers as well) can't know all the words in the language, and non-natives usually have a smaller receptive vocabulary than a native speaker.
