It's hard to tell how quickly you are learning a language, while immersed in it. Sometimes it feels like you are a sponge absorbing knowledge at an alarming rate. Other times, it feels like there is no possible way you could be learning less.
When I first got to Spain, I had no idea how to order food, what I was looking at on the menus, and could barely communicate on even a basic level.
Today, I aced a job interview in Spanish! I didn't use a word of English, the interviewer didn't speak any English. The interview was for a position as an English teacher, so they are very used to people who speak Spanish as a second language, but I negotiated a contract, talked about my experience in Japan, and even made a joke.
I love learning Spanish, compared to Japanese, it is incredibly easy. The grammar makes sense, the writing system makes sense, and there are many cognates between English and Spanish.
I am nowhere near fluent in Spanish. But, I am coming up on conversational, at the moment, I am able to hold a basic conversation with anyone with some patience... and that feels good!
