Learning your first language
When I joined Duolingo was the first time I intensely studied a language. I knew of few words here and there of other languages but nothing substantial. I've never tried to learn one before except for one time I borrowed a language cd of fifty words from the library.
I got that moment recently when I was like, "I'm actually learning a language!" when watching a video in Hebrew. That moment when it wasn't just foreign but some language you actually understood. It wasn't that I knew much, but that I connected with what I did know. I was sure about it. It wasn't like I know that word, but it's still hazy in my brain because I don't know it well. I was sure of it and it was reality.
It's that moment when wow, the language is yours in life besides all that typing and learning and reviewing in Duolingo.
Congratulations, and Mazel tov! It is indeed a delight - that moment when you recognize learning in the real world!
I once started to type a word in the target language instead of English, I laugh so hard when I realized what I have done. Another time I mange to do the 2-3 first skills of a tree in "test out" mode, where less than 3 months prior I knew nothing about the targeted language.
